Not sure exactly how it decides which ability to display, whether it's the last hovered over or whatever pet is adjacent to it in the inventory, but this is purely a graphical bug. When you exit your inventory, the pet will correctly show as having no ability.

Expected Results: No ability should be shown, hatchling pets do not have abilities yet until they evolve to the next l evel.
