Have you tried to create an issue in github? I was going to create, but I thought that you might you want to do it yourself.
Yes, I wanted to create an issue on GitHub, but I didn't understand what "gen-l10n configuration" is, so I didn't know exactly what information was required to create the issue and resolve the problem. So I didn't write anything there.
However, it seems that fixing the issue with the Czech system language also resolved the problem with Russian. I updated the app today, and the transaction history is now displayed correctly.
