I see a lot of text with basically one problem: Kodi seems to forget settings from time to time.
I also see that the first rule of submitting a problem has not been met: where is your debug enabled kodi.log file?
No kodi.log provided means nothing to investigate.
Lots of people have an opinion on Estuary, Kodi's new default skin. Which is fine, if you don't like the skin, choose a different one. Maybe your repositories need to be manually refreshed first, after which you should have access to all Kodi repository addons, including all skins with Confluence as well.
