@Ubuntu_ard Are you looking at non-English speaking countries? OpenStreetMap is meant for navigation, where street signs would be looked at frequently. Having English street names in Iran is a pretty useless idea.
If your system language is non-English that could be causing it as well. In which case you can set the locale from terminal and run Maps from there.
Fosstodon is a Mastodon instance that is open to anyone who is interested in technology; particularly free & open source software.
