As said before is not a minix problem.
Kodi is always in evolution and add-ons also.
Sometimes we have an update on something and may brake other thing (or even don't work anymore with a particular version)
You can do these :
-wait for another add-on update (recommended for kodi 18.4 stable)
-try other kodi versions (not recommended, might be unstable- kodi 18.5 or kodi 19)
But i advice you staying for now with kodi 18.4 release , is very stable in my opinion.
I advice you also staying with default (i almost sure default settings are this way) add-ons settings - install automatic updates
