Private message the commish and ask for an explanation.
There is no reason for add/drops to get reversed just because "oops, I didn't mean to do that".
If the commish doesn't do something about it, I would point it out to everyone in the league. Not in a cry baby sort of way, just that you think that the actions were wrong. Let everyone else draw their own conclustions about the details. It will be apparent to them and you may get some support from other owners.
In that scenario, the commish is more likely to rescend his actions.
