Bug with confusion and single strike scroll

Firenote01

So I dont know if this applies to other types of attacking tool cards, but when i was testing out a deck i played against a single strike urshifu deck. I confused the attacker who had the single strike scroll card with furious anger. The user flipped tails and 30 damage was dealt, but for some reason, I still got attacked by furious anger, which shouldn't have happened. So this should be something to look into because this problem could possibly be the same with other type of tool cards that attack like other scrolls.
