There is also an error in the 'cancel' operation for the 'Cabal Coffers'

When you tap two Swamp , generate two black mana , then tap "Cabal Coffers" and use these black mana to activate the ability of "Cabal Coffers" .You will gain a lot of black mana.
But if you press the cancel button at this time，you won't untap Cabal Coffers“，and you will get two black mana.Then if you press the cancel button twice again, two Swamp will be untap，and you will lose two black mana.This operation is obviously incorrect.
I am sorry and this is my second feedback on this bug, mainly because I noticed that it was marked and fixed in the previous feedback. However, I tested it on the Android platform and found that the bug still exists.
