A Translation String doesn't show
This is a screenshot of this issue. It shows that the section "Arpeggios & Glissandos" in the palette showing an original string instead of the translated one.
This doesn't only happen in ZH-hans Chinese but also in JP Japanese, which most part has been translated.
This string was normal before 3.1beta.
Note: I am one of the translator. I'm sure I have done the translation thoroughly.
