Tags not allowing changes

Have run into issue with Tags just in the last couple days. I have a bunch of appts in my calendar I switch tags on regularly, and I can no longer do so. I’ll change the tag and click Save, but it just goes back to the tag it had previously. I also saw that I can’t even change the name of the appt, it also changes back to the previous name. I removed and re-added the profile, and reinstalled the app, without success. Any ideas?
