The Red Candy Apple recipe is listed twice on the Greek Oven for some reason - the second listing for it is just a blank box without any preview image or anything in it. The duplicate recipe listing also seems to remain even once the other new recipes are unlocked.
1st image is a photo of the duplicate before all recipes are unlocked
2nd is how the duplicate appears after unlocking all recipes.
Not sure if this is a bug since it doesn't seem to be impacting game play but figured it's better to raise awareness on the matter regardless.
