FF6Tools - Browser-Based ROM Editor

Oh, thank you very much for making the online version of the editor. I used it to edit dialog of FF5 RPGe on my phone. But I found some issues：
-When I change the "Black Belt" that shows when you get the Pieces of Wind Crystal to "Monk", the "Black Mage" become "ラck Mage".
-Another issue I've found is that whenever I do some changes on dialog, the line "What's that?" of Butz in the first cave which leads to Pirates' Hideout become something else, which seems like part of the lines of Exdeath.
I don't know it's due to my phone or the browser I used or the editor. I use an android phone, I've tried the Edge and Chrome for android and the issues always occur.
