I have a very strange issue with my Jira Software Server instance. I got a report from a user that Component Watchers were not being added to issues. I went to Admin -> Apps -> Manage Apps and found that suddenly, four of my apps are listed as incompatible with the current version! I upgraded my version of Jira to 8.1.1 in early May, and at that point all apps were updated and had no issues. How could this suddenly happen?

Investigating further, I went to the Latest Upgrade Report page and saw that it was now telling my upgrade to 8.8.1 occurred on 15-Nov-2019. This version wasn't even released until April 2020!

Any idea what could have possibly happened?
