I think this is the same problem as when something is RG at species level and someone then adds an ID at subspecies level. It appears to become RG at subspecies level because the green banner appears next to the ‘observation ID’ (or whatever you want to call it) - but actually the community ID remains at species level (or complex level in your example) and this is what RG ‘officially’ refers to. It’s been discussed in quite a few other threads, I’m sorry I can’t find the links right now. But I agree it’s unhelpfully confusing (even GBIF is apparently confused by it…)
Welcome to the forum btw!
