Mod lover

Hey guys. I made a account to ask this ( I didn't make one as the mod with the monkey avatar scares me) but I need help. I have install this into my main ksp on stream and loaded an existing game. I landed a satellight use the fairing and then another one to connect to to it. But when I targeted it (they didn't have e fairings still on) it did not highlight it in green or gray and I could not see how far away with it.
