I use Vortex with no issues at all, all my 7-8 mods works flawlessly. However I have not used the hair mod or the UI mod. It's probably the mods in question and not Vortex itself. Vortex SHOULD remove all mod files if you uninstall them from via Vorted. If you still have problems, you'll have to scrub the folders for mod presence manually. Uninstalling the game won't help if the mod files are still there making a mess.
