Kodi shows updates available, when there aren’t any

Why is it that some add-ons show up as needing an update, but when I go to click update there are no other versions available from any other repos that I have installed? I even get this error at the repo of the author of an add-on – how do I fix this?

I did the database fix on Kodi:

SYSTEM > File manager > Profile directory > Database.

In here I selected all the files which ends with a “.db” suffix and deleted them one by one and restarted kodi, however the same updates are listed after a few minutes, so that did NOT fix it.

Any ideas?
