Scheduler issue: Can't change date range in scheduler

Since last week, I haven't been able to change the date range in my 'Any host available' scheduler. 

When I try to change to the date range in the 'Availability' tab, I can no longer click on the 'Finish' button.

I can click on the 'Previous' button, but not on the 'Next' button.

If I click on the 'Previous' button and try to push 'Finish' in the 'Host' tab, I am taken back to the 'Availability' tab, where the same issue persists.

Note that this is even the case if I remove all date overrides in the past and change the schedule to not include any past dates.
The issue is the same in Safari, Chrome, and the Zoom app (Mac).

Help!
