My game says I own 12 of each broom I have bought. Any ideas on where to edit to fix?

I think it somehow is linked to the fact that you max out at 12 items per tool slot when pressing the tab button. I don't know how it applied that to the brooms,

 

I bought all the brooms available from the shop in Hogsmeade, even though I wanted the one sold by Arn. But now I cannot switch between any broom from the first one I bought & it says I own 12 to 24 of each broom, including the one I got from doing the first challemge. I probably have over 100 brooms & can only use one, LOL.

 

Any way to edit the game files to delete all these extra brooms? It would be nice if we could sell them, but nooooooo.
