Hello TheMachPro.

From our FAQ:

When should I mark a gift I won as "Received" or "Not Received"?

• You should only mark a gift as "Received" when you have both (i) received the exact game described in the giveaway, and (ii) activated that game on the Steam account you used during registration. In all other instances you should mark the gift as "Not Received" one week after the giveaway has ended.

You should not be marking giveaways as "Received" if you didn't actually activate a game/DLC for yourself, and you certainly shouldn't be marking "Received" and then removing that mark. Please be mindful of this in the future.
