Did you get the Quest before or after you had completed buying them all? Perhaps, it may be a bug.

To know for certain, try this. Search the store. Find one of the found items from the store in you closet and sell it. See if it will reflect in the store info. Reload the game if necessary. Hopefully, when you do, you can buy it again. AND finish the quest.

Please, write back if the solution above was successful or not.
