iD incorrectly offers to upgrade London Underground stations to London Overground

For at least Oxford Circus:

Although not Great Portland Street (presumably due to the lack of operator):

I assume this is because an underground station:

public_transport=station
railway=station
station=subway
subway=yes

Is essentially a subset of a railway station:

public_transport=station
railway=station
train=yes

I'm not sure how to fix it short of tagging train=no it turns out you can't actually solve it with not:operator:wikidata as it also matches the Elizabeth Line ( https://nsi.guide/index.html?t=transit&k=railway&v=station&tt=eliz#elizabethline-abdde3 ) and it doesn't support semicolon or comma listing of multiple values.

This is probably related to the iD-specific behavior described at #9996 (comment), so I'm not sure if anything can be done about this on NSI's end.

Great Portland Street doesn't include a network:wikidata at the moment, so I expect that's why no suggestions are taking place. Adding the underground network:wikidata causes the same suggestions to override with the Overground and Elizabeth Line.

Clicking not just seems to rotate between Elizabeth and Overground continuously.

Yeah this does seem to be an issue only with iD. If the station already has network and operator values, I don't know why it would want to switch London Underground and London Overground.

I tested this station in Rapid and I don't get the issue:
