A when() query doesn't work properly

Hey!

I have this query

ReviewReports::when(
                isset($reason) && $reason != "all",
                fn ($builder) => $builder->where('report_reason', '=', $reason)
            )->when(
                isset($status) && $status != "all",
                fn ($builder) => $builder->whereHas('review', fn ($builder) => $builder->where('report_status', $status))
            )->where('solved', 0)->orderBy('created_at', 'desc')->with('review', 'user')->get()

which isn't working properly. I'm not getting correct results. Is anything wrong with it?

That's the form

<form id="sortForm" autocomplete="off">
              <div class="row">
                <div class="col-12 col-md-2 col-lg-2">
                  <div class="form-group mb-0">
                    <label><i class="fa fa-sort"></i> Sort by reason</label>
                    <select class="form-control" id="selectReason">
                      <option value="all" disabled selected>All Reasons</option>
                      <option value="harmful_illegal" @if(request()->reason == "harmful_illegal") selected @endif>Harmful & Illegal</option>
                      <option value="personal_information" @if(request()->reason == "personal_information") selected @endif>Personal Information</option>
                      <option value="advertising_promotional" @if(request()->reason == "advertising_promotional") selected @endif>Advertising</option>
                      <option value="inappropriate_media" @if(request()->reason == "inappropriate_media") selected @endif>Inappropriate Media</option>
                      <option value="other" @if(request()->reason == "other") selected @endif>Other</option>
                    </select>
                  </div>
                </div>
                <div class="col-12 col-md-2 col-lg-2">
                  <div class="form-group mb-0">
                    <label><i class="fa fa-sort"></i> Sort by status</label>
                    <select class="form-control" id="selectStatus">
                      <option disabled selected>All Statuses</option>
                      <option value="0" @if(request()->status == "0") selected @endif>New Reports</option>
                      <option value="1" @if(request()->status == "1") selected @endif>Under Investigation</option>
                      <option value="2" @if(request()->status == "2") selected @endif>Investigation Finished</option>
                    </select>
                  </div>
                </div>
                @if(request()->reason || request()->status)
                <div class="col-12 col-md-2 col-lg-2">
                  <div style="padding-top: 30px;">
                    <a href="{{ route('admin.reviews.reports') }}"><button type="button" class="btn btn-danger">Reset</button></a>
                  </div>
                </div>
                @endif
              </div>
            </form>

I'm using jQuery to send the form.

      $("#selectReason").on('change', function() {
        var reason = $(this).val();
        var status = $("#selectStatus").val();

        if(reason == null) {
            reason = "all";
        }
        if(status == null) {
            status = "all";
        }

        window.location.replace("{{ route('admin.companies.reports') }}" + "/" + reason + "/" + status);
      });

      $("#selectStatus").on('change', function() {
        var reason = $("#selectReason").val();
        var status = $(this).val();

        if(reason == null) {
            reason = "all";
        }
        if(status == null) {
            status = "all";
        }

        window.location.replace("{{ route('admin.companies.reports') }}" + "/" + reason + "/" + status);
      });
