With regard to rendering, both “stations” and “station buildings” are shown as stations, but it’s obvious which is which based on what you see when you either move the cursor over the object on screen, or search for it.
With regard to routing you’ll either pick a destination from the screen (after moving the cursor there) or more typically via a search menu. After this change the “ground transportation” menu now has “station buildings” as well as “stations”, but there aren’t that many railway stations.
Yes, that is an issue - and there are also false positives doing it this way - this is actually a tourism-only station that would normally be excluded, and this should be excluded (but currently isn’t) for being only historic.
