When putting an item down for a fox, item disappears but is not in Fox's mouth, it is deleted from game, even upon killing the fox after it "picks up" item that disappears, item is just gone. When spawning in a fox that has item in mouth, if you give it food, food disappears and item stays in fox mouth I stead of fox dropping item, picking up food into mouth, and then after a short period of time eating the food leaving mouth empty. If you are trying to get fox to hold a sword in mouth, the sword disappears like fox picks it up, but item is not in mouth, and sword enchantments do not work if it kills chickens (fire aspect II to cook chicken)… the sword does not appear in mouth, sword item is gone, not recoverable..

Expected results, fox picks up or swaps items in mouth and carries it until swapped with another item, if item is food, fox eats food after a minute or so, items do not disappear and should be recoverable by trading items with the fox or fox dies.
