No, I wouldn't delete anything. It's 17gb because I needed to included every possible option that could be used.
Yellows are fine. In fact, you will have all yellow and green when it's done correctly. Reds are not okay. I assure though, every mod is included, so it's definitely something you setup wrong. Check the Installation Tab and be sure that all the locations are pointing to the correct directories. That is literally all that needs to be done to get rid of reds.
The only other thing I can think of is that you still have all the mods extracted from the .rar, .zip, .7z files, which is wrong. It will not change the colors if that is still the case.
