Help with installing some mods

Hi! Not new to Sims 4, but new to using/playing with mods/cc.

Most of my mods/cc are in with no problems and working the eye they’re supposed to be. But I tried putting in some CC Skintones eyelashes and I cannot get them to work! And because I used the no EA eyelash mod, now my sim doesn’t have eyelashes at all and after fighting with this over an hour I have a headache, lol.

Any advice/suggestions? Very much appreciated!
