cheryl healing bug

I have noticed with the supporter card cheryl that when i use it to heal a damaged evolution pokemon it will discard any and all energies attached to my pokemon even if they are a basic or not damaged.

for example, i played a game last night where my active was the basic entei v who was damaged with 2 energy attached while i also had a damaged skeledirge ex on the bench with 2 energy attached. cheryl healed the skeledirge ex and discarded energy as expected but did not heal entei v however entei v's energy was discarded.

and recently i had a skeledirge ex in the active with damage and 2 energy attached as well as a skeledirge ex on the bench with 2 energy attached and no damage. i played cheryl which healed the active but discarded both skeledirge ex's enegies.

this is a deck breaking bug with cheryl as neither time has it played properly and cost me the game both times.
