I used quick stock to try to put my items in my gallery but they don't show up there. Instead they are all in my other shop? Not sure how to put items in my gallery so people can see them or even so I can see them in there... I was pretty sure I was in the right shop to do quick stock, so what happened and how do I fix it?

You probably used the quick stock option from your regular shop... You'll have to move everything out by "hand" since there is no option for doing this quickly.

A gallery has its own quick stock option (which says move to shop as well...) or you can just choose from your inventory the "move to shop" -> "choose -shop name here-" which should be your gallery :)

Thanks!
