Using a Mega Gengar Deck but opponent is still taking prize cards

Arqdos

Playing on TCG-live and I am baffled. In what situation would Mega Gengar's abilities be disabled? I fought a Ethan's adventure deck and Ethan's typhlosion knocked out my Pecharunt EX and Seviper but on each of those knock outs they were able to take two prize cards and then 1 prize cards but all those time i had two Mega Gengar in the bench. Is this a glitch because i search each ability card in the logs and there werent any blocking Mega Gengar's ability.
