Hearthstone Mercenary App bugs

My Hearthstone game is having significant problems in its gameplay.
The first problem is that when playing a heroic game, specifically heroic Rotimer, the rivals bleed damage is five times stronger than listed. I have a red character, he is attacked by a red character who has a bleed 10. My characters are taking 50 damage when they have not attacked each other 5 times in one turn.
The second problem seems to be a server issue. I go into the mercenary area to use the currency gathered for a mercenary. I click the button to upgrade, it gives me the confirmation, then does nothing. No upgrade to the character, no points used.
I once asked tech support to remove the ability to play hearthstone from within World of Warcraft. They did so. I am curious if this has caused bugs within the software that are causing the above issues. If so, go ahead and add the ability to play hearthstone from WoW to fix the issues.
From an end user standpoint. it seems like your hearthstone servers are old servers that do not take user instructions very well.
