Bad Profile is haunting me.

Hi guys. I have had Kodi for a few years now and usually update it without any issues. I always use a specific self installing add-on. Just recently, I noticed that one of the movie add-ons skips a bunch of good links and either plays something in crappy quality or won’t play anything at all. By good links I mean that they’re known working links that I tried on our main computer and my phone. I completely deleted Kodi along with the user profile (appdata/Kodi) and any registry files I can find. Then I did a fresh installation, installed the add-on again, etc., but again, it keeps skipping links. It does this for every movie.

I created a new user account/profile on my computer and installed everything the exact same way. As soon as I click on the same movie, the very first link works. This is was led me to believe that I have a bad Kodi profile or something similar on my first user account. Am I missing any Kodi folder when I delete everything? Has anyone else had this issue?
