v-if function returning nothing, but it should

Hello all! Running into an issue that's been bugging me for the past 2 hours.

I've got a function in a mixin like so:

 checkPermissionMeetings(type,areaID){
            if(this.$store.state.global.permissions.meetings===true) { //If user has basic meeting access
                if(type==='write'){
                    Object.entries(this.$store.state.global.permissions.meeting_areas).forEach(([key, val]) => {
                        if (parseInt(key) === parseInt(areaID) && (val === 'write')) {
                            console.log('write_true')
                            return true;
                        }
                    });
                }
                if(type==='read'){
                    Object.entries(this.$store.state.global.permissions.meeting_areas).forEach(([key, val]) => {
                        if (parseInt(key) === parseInt(areaID) && (val === 'read' || val === 'write')) {
                            console.log('read_true')
                            return true;
                        }
                    });
                }
            }
        },

I am calling it in a view component which renders a navigation bar:

<span v-for="area in area_meetings">
						{{area.id}} {{$store.state.global.permissions.meeting_areas[area.id]}} //This is here so I can see that I am sending the correct values to the function
                        {{checkPermissionMeetings('read', area.id)}} //This is here so I can see the output, but it returns nothing
                        <router-link tag="v-list-item" link :to="'/meetings/'+area.id" class="ml-5" v-if="checkPermissionMeetings('read', area.id)">
                            <v-list-item-icon>
                                <v-icon>mdi-chair-rolling</v-icon>
                            </v-list-item-icon>
                            <v-list-item-title>{{area.name}}</v-list-item-title>
                        </router-link>
                    </span>

I've console logged the outputs as you can see in the code, and they are looking ok. I have also put the function in curly braces so I can see the return, but this returns nothing at all.

I can see them in my store

I'm even echoing them out on the render and the values match...

Is there something fundamental I'm missing here?
