I think it’s the new behaviour since the Actions dashboard was introduced. Copying components will keep the action as it is. If you wnat to make a copy of the action, do it in the Actions dashboard and assign it to the new component.
it was always like that… even years ago… it comes and goes away… but now it is for more than 2 weeks… just don’t trust copy elements too much… also publishing and stop publishing… it might mess up your App
