Duplicate Hired Merchant open -bug

Hi!
Today I was opening a store in free market. When I wrote the name and clicked OK I got disconnected by server lag.
When I logged back there was no shop at the place where I put it.
When I try to open it again it gives me the message saying that my store is already open. I cannot close or even find it.

screenshot of the message:

 

Can you go back to Frederick he will probably have items for you.

 

I did not have a shop open and frederik just says that I havent sold anything yet :/

 

It will probably automatically "close" the store after 24 hours and I can open it then. Still, pretty annoying

 

Same happened to me lastnight, by morning he changed his mind, seemingly.
