Android system keyboard shows english language

[Davronito]

Hi guys! I've created an app for Android with Qt C++/QML. I placed a TextInput. My android has only one Language and input language = Russian. When i press on the TextInput, the system keyboard is appearing in 2 languages that by default is english. Why? Does Qt or QML has additional add-ons in them?
Here're the screenshots:

And I've found the point of this case: it was because of "inputMethodHints: "ImhNoPredictiveText" ". But why it adds english keyset to my virtual keyboard, I didn't catch it
