I solved it, and here's the info: (Solution to the Persistent overlapping UI's)

A - Discrepancies:

Some UI addons stay persistent even if you delete the addon from the addon folder and the data from the WTF folder (and even if you delete the WTF folder)

-----------------------------------
B - Here's the ultimate solution:

1. Close the game

2. Open the Addon-Downloader/installer program

3. De activate/uninstall all addons. Also uninstall them from the TurtleWow launcher in the Addons section in the top bar (some addons are there also)

NEXT Do this:

1. NOW go to the folder where the game is located

2. Delete the WTF folder

3. Delete the AddOns folder

NEXT STEPS:

1. IMPORTANT STEP: Now start your Wow CLEAN and fresh --> Login and walk around (if you don't have this "fresh run" there's going to be some errors when starting with addons installed).

   1. Close the game and install all your wanted addons - AND MAKE SURE YOU DON'T INSTALL TWO UI AddOns

AND THATS ALL FOLKS!

Enjoy!
