Forum:Dark Law Question

I'm pretty sure I know the answer to this, but I just wanna double check. So Dark Law's effect says "Once per turn, if your opponent adds a card(s) from their Deck to their hand (except during the Draw Phase or the Damage Step): You can banish 1 random card from your opponent's hand".

So I assume I can only do this effect once even with multiple Dark Laws. However I was playing Ygopro.co vs AI Fire Fist and they added a card to their hard while I had 3 Dark Laws. However YGO gave me an option to chain 3x Dark Law's random banish effect and I ended up banishing 3 random cards. So i'm wondering if that ruling is correct? or is that just a glitch?
