Medium Cake Pet Duplication and Deletion

Description of the bug: (optional screenshot/video): Hey guys, today when I tried to put my two cake pets in Cash Shop storage, one of them got deleted and replaced with a clone of the other cake pet that is unusable with original one.

What is supposed to happen?: The cake pets are suppose to be able to be put in Cash Shop storage without one being deleted and replaced.
Where did you find and/or notice this bug?: In the Cash Shop.
A step-by-step guide to re-producing this bug (optional): I don't know how this happened for sure, but I would try getting two cake pets and make an attempt to put them both into the Cash Shop storage at the same time and then taking them out.
Extra information (optional): I don't know if this is very significant to reproducing the bug, but when I tried puting both cake pets into Cash Shop storage the first time I got a message stating the the action could not be completed due to an unknown error. When this happened I decided to try to take the first cake pet(PartyAnimal) out of Cash Shop storage and put the second cake pet(BakeSell) in first which seemed to work. After I took both cake pets out of Cash Shop storage again, I noticed I had two of the same cake pets.
