How can I change default road map language?

On my smartphone (Android 10) the default system language is Russian. I downloaded the road map for Georgia from OpenAndroMaps. XCTrack showing me the road map only in Georgian. The map for Georgia includes 3 languages: Georgian, English and Russian. I have been checking the map in the Cruiser application. It showed me all of them. But XCTrack showing me the road map only in Georgian. I have been changing the default system language to the English on my smartphone. XCTrack again showing me the road map of Georgian language. How can I change default road map language in XCTrack?
