By in app icons, I mean the actual icons inside of the KWGT editing app. In particular, the Global and Calc icons have been replaced with Chinese characters, as have several others. I am on a Huawei Honor 8 so it is possible it's some sort of system font problem, though I have not seen this happen in any other app.
Looks like your device overwrites some default Android Icon, i might be able to fix this once i will have fully migrated to a new icon pack i am currently using
Fixed in 3.29
