Basically, there are two schemas for mapping public transport routes, v1 and v2. The tag `public_transport:version=` is for specifying which one is used.

For these two specific relations, they are actually broken (missing/no stops), so (iirc) they fit neither of the schemas. So no `public_transport:version=`. The way to fix it is to map it properly (i.e. add stops, also check if the route is correct), and add back `public_transport:version=2`. Which I will not be doing anytime soon because bus route mapping is painful.
