Edit Text Style issue

Maybe I'm just missing something here (probably), but it seems that not all of the text style edits work. Mainly, I'm trying to make the dynamic text (pp, mf, f, etc.) smaller as it seems much too large at its default. I've changed the "Dynamics" text style and nothing seems to happen when I hit "apply". Even closing and re-opening results in no change. I don't see any other text category that the dynamics text would be under. I have tried editing other text categories just to check and "Chordname", for example, works just fine.

Is this a bug, or am I missing something painfully obvious?
