[Bug] Eternatus's PP Flyout does not Reset Upon Form Change / to Reflect New Moveset

[Snailman11]

Describe the bug

Eternatus's PP Flyout continues to display PP used from its initial moveset.
-As new moves are used, they're added to the box from left to right / top to bottom.
-If it uses the same move again, PP for that move is updated to reflect the true value.
