Can't detect QML module registered by qmlRegisterUncreatableMetaObject

I register my namespace enum using qmlRegisterUncreatableMetaObject.

When I edit QML code in Qt Creator, it:

1. Shows me "QML module not found" warning at the module import line of code
2. Does not show suggestions when I try to use enum.

Anyway, my program works fine. So all the things are correct in my code.
