Translation of entities (CDS) ro Russia is a disaster, You have to hire more professional translators. And it is not matter of prefectnes but matter of workability. For example: Account entity translated to russian as "СЧЕТ" which means INVOICE ))) It is imposibble to build apps basing on such inadecuate translation as You understand. And that's just one of much more examples...
Do something with that.
Also, to avoid this problem I tried to reswitch interface to English language and that worked but for start page only, when I go to apps editor, interface gets back to Russian with all translation crap followed.
