Anyone else losing their mansions when storing

Yes, this is happening to me too! I think my other buildings keep turning into Deluxe Condos, because I have like 15 of them (it fluctuates) when the max is supposed to be 10. I had 17 at one point, but then it dropped again and I got a Classic Mansion back. I have a couple of extra Car Parks too. I thought it was only happening to Level 1 buildings, but since it happened to you with Level 5 buildings, that disproves my theory.
