the problem is that AM always shows 0.00 profit/revenue for any miner that switches to any of the Zergpool stratums
I have the same problem on my side
Awesome Miner had some code for zergpool left since before so the profit calculations will indicate zero even when adding it manually.
I'm just about to release a new version of Awesome Miner where Zergpool is available again via the Options dialog, Profit Switching section.
