Once UltraModManager is setup and working, get rid of and stop using NyxLauncher. They are not compatible.
Specifically any mod settings added via UMM WILL get wiped out of existence (at present, the setting to toggle whether or not UMM pops up at game launch)
Also, at present (that I know of) the only mod that supports the mod folder getting renamed (thanks to the features in UMM) is the latest version of
Cheat Menu Framework
(the release on github)P.S: Attach screenshots of your mod file structure for the mods that are not working. Mods expect a specific path unless coded otherwise.
