Yes, very misleading. "Cukup kamar" struck me as a very strange expression, but I thought for a moment that maybe, just maybe, it could be used to mean "enough space" / "enough room". Luckily I saw your comment, which suggests that this is not the case, before I actually learned to use this absurd expression. I'll use the report button.
I'm still not sure if the same considerations apply to "cukup ruangan".
