Dunno why but recently all my bundles, some mods and extras appeared as games in my library. So when I have Warcraft I and II as games separately I do have also them as Warcraft bundle. What happened?

It may have to do with how exactly GOG Galaxy add games: through a gaming database that, in this case, seems to separate different games. Isn't that a good think anyway? The mods and extras are a bit weird though: could they be considered like 'standalone mods' or something like it?

EDIT: If last answer is no, it might be a bub, worth it to be 'send a report' to the devs, listing the games you remember.
