Does anyone else in your Kinship have decoration permission?
I believe, but I'm not totally sure on this, that if someone tries to remove or replace a decoration item that's bound to another player then it automatically gets sent to that player's Escrow. It could be that someone in your Kinship tried to remove the items in question for some reason.
