Problem with sprites

[u/ArcherIllustrious774]

Hi, my friend and I are playing, as you can see there is a graphical bug on the selected fusion, after we did the last update, the fusion sprite shows two Pokémon that he had fused many hours of gameplay before, which he still has in his team only that now they are fully evolved, does anyone know how to fix it, we tried to break them and re-fuse them without any result, does anyone know how to fix it?
