I have never done this before but I do use itemID numbers in MM so I'm curious. Did you account for the fact that if you're copying somebody else's mod that uses monster sets have you looked at enough of the mod so that you're actually telling the game what the trial set is?

Just changing Monster to Trial as far as text goes will for sure change the text, but how are you telling the game all of the different ID numbers for all of the different trial sets so that the filter works correctly.

Now on the other hand it is a constant for a filter type and not an ID number, ignore what I just said.

Other than you may want to double check that you're actually telling the filter that it's trial set and not a monster set cause I have a feeling you have to define that somehow.
