So I just started playing last night. Today I was able to unlock the second salon design and when I purchased it, I was asked if I wanted to change my salon with the new design. Of course I picked yes.

So I started to purchase the new items and sell the old items. However, I went to sell my old styling chairs to install the new ones already purchased and opened, and I keep getting a message saying that the chair is being used by an employee and to purchase a new chair first....WHICH I DID!!!?????

Please what I am doing wrong here???
