Today is Monday. For the first time, our schedule filled up for today and for Wednesday. This made the date red on the calendar. We needed to cancel some appointments, but they are still grayed out and unavailable (and the day is still red). We then deleted some appointments, but the time is still grayed out. On Wednesday, we added more appointments at the end of the day. The day is no longer red, but any appointments that were cancelled are still gray and unavailable (we canceled some through the email and also cancelled some manually through the admin panel) We also added more time to today's red schedule (just like I did for Wed), and any new time added was grayed out and unavailable. This seems to be some sort of glitch or bug. Once a day's schedule is full and turns red, the system does not update the calendar when appointments are canceled or deleted. It also does not allow cancelled appointments to free up the same day. Here are Screenshot of Monday May 11 in red with all appointments grayed out, and screenshot showing 2 canceled appointments  https://paste.pics/b8db157fb1a04f3ff182b55b2b979b56 https://paste.pics/f99f0f6982d8cca8a0c7073f45351cce
