I don't know if it's my problem or something else, but with the Chinese Simplified and Chinese Traditional, the four control buttons at the bottom of the game are all □, and the dialogue options are all □□□, at least for Android. The translation of this passage by a translator may change my meaning and cause confusion.
Hi, I just checked this out and it seems you're right. So sorry about that!
This is common in the Android Builds as the font for the quick menu at the bottom changes and doesn't match the rest of the game. In the next update, the quick menu will be changed to English until I come up with a solution. Thank you for pointing this out!
