Calendar Issue - Provider In Office Setting Not Working

When I try to input a providers in office availability for scheduling in their calendar in minutes, it is creating availability for the rest of the day. (see attached pics) I tried changing the availability time frame to 60 minutes and 180 minutes and it produces the same calendar results. I don’t think this is user error, but I could be wrong!

This is a known issue (provider in office calendar event duration bug · Issue #1653 · openemr/openemr · GitHub). Anyone find a way around it?
