Bug with modifiers to damage (only)

There seems to be an issue with powers that modify the damage modifier.
For example on Wolverine 97:
If you toggle on either the Attack Stance or Focused Fury powers, you will see it bump the damage modifier on the sheet, which is correct.
However, if you hit the Melee Attack score button to roll, it is adding that doubled amount to the dice roll total as well as to the damage.
From my understanding of the power, it should only be affecting the damage, not the dice roll total.
For example with Attack Stance on, Wolverine 97 should be getting +6 to the dice total (his normal melee ability modifier) but +12 to the damage calculation (double his modifier to damage), but the dice result is adding 12 to both.
Or have I missed a rules clarification somewhere and it should in fact be counting to both?
I know there’s lots of errata out there.

Thanks for the report, I’ve got a request in for us to investigate this further.
