I'm assuming I'm supposed to put them on elevated rails since that's what the research shows, but whenever I try to place one, it just says it's not connected to a rail, and it doesn't function. Am I just doing something wrong?

I meant the trapdoor switch, I'm a little dumb.

That's odd, do you have any other mods that might adjust collision boxes of rails or rail signals? That's the only thing I can think of

Nevermind I'm actually even dumber cause there's a typo that's been in since release causing the Trapdoor switches to not actually work ever lol. Try it now on 2.1.5

btw the switch will say it's not connected to a rail in the tool tip but it's not related to the functionality and I can't disable that message. It should just work when Trapdoor wagons roll over them
