Transmogrifier Drop-down Set List not Working

[ghost]

When enable Masque: Caith plugin transmogrifier set list isn't expanding.

[StormFX]

Masque: Caith doesn't affect the transmogrifier UI.

I think this is an indirect bug.
A friend confirm same issue:

• Masque enabled no problem
• Masque Caith enabled transmogrifier set list isn't expanding.
  For information "FR" client

I'll check for others addon side effect on this bug and tell you more

I'll see if there's a typo in the frFR file.

Update: I just checked the locale files and with my client set to French. It works fine on my end. Disable everything but Masque and Masque: Caith.
