Krusty Land Glitch

I have just noticed a glitch, I don't know if it has already been reported..
So if a character (eg. Kearney) is at Krusty land on a quest, it shows Kearney in the premium item purchase list for 60 donuts even though I already purchased him.. This also is the same for Krusty, he is visible for the purchase of the Krusty burger building even though I have him on a quest at Krusty land.
Don't know if this has been mentioned but I thought I would.
