Mimikyu V Dummy Doll and Path to the Peak incorrect interaction

I recently played a game where I placed Mimikyu V, activated the dummy doll ability when I placed it into play and then my opponent on their turn played path to the peak and was able to damage my Mimikyu V. This is not how the cards are intended to work. The rulings compendium states:

"Say I played Mimikyu V and used its "Dummy Doll" Ability on my turn. Then on my opponent's next turn, they play a Path to the Peak stadium. Does that cancel the effect of "Dummy Doll"?

Since the Dummy Doll Ability activated and placed an effect before Path to the Peak came into play, its effect remains."

And so, I hope this error can be addressed.
