Not sure if this Issue / PR was assigned but as per the linked issue, even the scheduleModal.svelte requires this fix.

Thanks.

@sourabpramanik, please make sure you ask to be assigned on the issue so that we can assign the issue to you and no one else tries to work on the issue.

And as @ItzNotABug said, the schedule modal also needs to be fixed.

Really sorry about that, I will be careful next time. I will take a look at the schedule modal as well
