Cottage living - animal wont come out of shed and I cant call it out

I placed a house from the gallery but it already had a llama in the shed, so I sold it, its been nearly 1 week in game since I sold the llama, a few in game days ago I bought a cow, I assigned the cow to the shed, the llama was still an option to assign aswell. The shed says it is occupied by an animal but I am unable to call any animal out, and no animal has come out. Im on xbox
