Hi!
I've written my issue as well as what I've done to try to fix it in this thread: https://www.reddit.com/r/kde/comments/8 ... t_working/.
If anybody here have anything in mind, please do tell. You can reply in this thread instead if you can't do it on Reddit for any reasons. I got email notifications enabled and on standby to respond to anything related to my issue. I've completely reached a dead end after trying to solve the issue myself these weekends..

This has been solved! Answer, for those who may need it: https://www.reddit.com/r/kde/comments/8 ... ng/e22l7hs.
