Some mods work some do not

[Cheif Operations Director]

I've downloaded some mods from curseforge and put them into my gamedata folder some of these mods works such as KIS Airplanes Plus but some such as EVE and probes plus  not work 

am I putting eve in the wrong place?

It's also important to note that somehow a second gamedata folder was created inside the normal gamedata folder.

Likewise chattered does not work either

Are there any files in the second GameData folder? Like the mods which don't work?
If they are there, move them to the original GameData folder.

EVE requires a config to run properly. Some other mods like SVE (Stock Visual Enhancement) provide their own config files for EVE, but if you install just EVE, you need at least the config files delivered with a previous version of EVE: https://github.com/WazWaz/EnvironmentalVisualEnhancements/releases/tag/EVE-1.2.2-1
(Don't worry about the version number, it is fine in this case. You just need the "EnvironmentalVisualEnhancements-Configs-1.2.2.1.zip", it will work with your EVE version as well. There is nothing special to these configs, install them like other mods )

If this doesn't help, a log file would be appreciated
