How to disable others languages while building qtvirtualkeyboard

Dev environment

Windows 10 64bit 19042.870
Qt 5.12.8(10) and Qt5.15.2

I'm trying to build qtvirtualkeyboard, and I just need English and Simple Chinese, I configurate it as CONFIG+="lang-en_US lang-zh_CN", it works well on Qt5.10.1. But since I use Qt5.12.8(orQt5.12.10),even Qt5.15.2, it can not work well, it always shows others languages such as:Japanese,Korean, Thai language, Chinese Traditional, like this:

I'm wondering how to disable the 4 languages. I've tried both CONFIG-="lang-ja_JP lang-ko_KR lang-zh_TW lang-th_TH" and CONFIG-="openwnn hangul tcime zhuyin cangjie thai" ,but it is till not work.
Do you guys have any idea?
