Thank you for checking the cause, appreciated. We cannot quite control what maps.me includes, things like this missing might be best reported to them.
By the way, the original developers of maps.me (MapsWithMe before that) forked it some time ago and now they develop Organic Maps - https://organicmaps.app/ .
It looks like maps.me, but seems to be developed more rapidly. I checked in Organic Maps, and this shop is present. Perhaps you'd like to try out Organic Maps?
You are also very welcome to discuss these topics in the chat of the Latvian OSM community: https://osmlatvija.zulipchat.com .

As the data in OSM is correct, closing this note.
