Unable to Edit Appointment Time

Hi. This issue started with the last update of Appointments+. When editing any appointment, the “start” time dropdown list shows “Unknown”, and when clicking on the dropdown list, the times displayed have nothing to do with my settings (every 30 minutes, or 15 when set by an Admin). Instead, the dropdown shows times like 08:27, 09:57, 11:27 and so on, which make totally no sense. I’ve just granted Support Access to save time. Thank you.
