Revenue/Profit display in main window

Not sure if this has been brought up, but i think the Profit is not being calculated properly in the main display per rig.

I have power usage specified in each profit profile specific to 1 GPU matching the same GPUs hashrate. (this is the proper way, correct?)

This way i get a good idea of revenue/profit for each gpu for each coin/online service.

Now when a rig with 13 GPUs in it is mining, the revenue in the main display is correct, but the profit displayed is subtracting only the calculated power usage of just 1 GPU/day from revenue, not 13.

Does this make sense, or should i give a few examples? I'm not sure if this is a known issue or not, or maybe i'm just configuring something wrong.
