Spark Subscription showing monthly - should be yearly

I am having an issue where the subscription panel is showing the yearly plan as monthly. For example, I have one plan for $10.00 / Monthly and the other says $100.00/Monthly <- should be yearly.

I have checked the SparkServiceProvider booted code and it looks correct and the Stripe subscription is set to yearly for that plan. I can see that the info is spawned in with plan.interval but I have no idea with this is not working.

booted() {code} Spark::useStripe()->noCardUpFront()->trialDays(7);

    Spark::plan('Monthly', 'monthly_1')
        ->price(10)
        ->features([
            'Our Monthly plan is a low $10 USD a month'
        ]);

    Spark::plan('Yearly', 'yearly_1')
        ->price(100)
        ->features([
            'Our yearly plan is a low $100 USD.',
            
        ]);

{code}

Any help would be much appreciated.
