Make sure you're doing the RCs with the right attitude. It's important to sincerely question whether you're dreaming or not and consider that the RC could go either way, rather than simply assuming you're awake and predict the RC to indicate that (because in a dream, it's likely to do just what you expect it will), or to do the RCs in “zombie mode” and not pay attention at all.

That may actually be normal. Most of my RCs in dreams are when I already suspect I might be dreaming and I want to be sure or gain more confidence that it's definitely a dream. Otherwise, the RCs tend to not work anyway. Which is a bit weird because it makes RCs sound useless, even though they're very important. The purpose of RCs seems to be more about getting your mind in the right position to be aware of yourself and your state than to just happen to do them by chance in a dream and have them indicate dreaming (which even then might not result in a lucid dream if you aren't already seriously questioning your state).
