Domains can change hands quite often. Therefore some of your domains might already be listed in a previous owners ParkingCrew account.
When you go to the Add Domains tab and some of your domains are already in another account you will receive notification that an ownership review has been started for them. Our support team resolves these ownership reviews on a case by case basis.

If you received notification about a domain being removed from your account that still belongs to you, please let us know and we will reassociate the domain with your account.
