The moveset calculator on Pokemon Database comes up with no results for Trick Room and if you search for Trick Room users after another move then it just changes the text and not the Pokemon.
This is an example in which the only Pokemon that can learn U-turn are said to be the only ones that can learn Trick Room.
I'm not seeing this problem myself, can you try again and let me know if you're still having issues? Also let me know what browser you are using.
