Shadow Mastery currently Broken: **Please Fix**

Shadow mastery currently does not work and I'll prove it to you.

In the picture I have the tooltip for rank 4 drainlife which without improved drain life deals 41 dmg/s for 5s.
Imrpoved Drain Life
41*.1 = 4.1. So this is 45.1 damage total and the tool tip says 45 to 46. Ok but I have 3 points into shadowmastery.
41*.06= 2.46. So total we should expect to see 47.56 dmg/s per 5s. The tooltip should look like this:
Transfers 47 to 48 health.
Seems to work fine for corruption. It doesn't work for Curse of Agony however. I have both improved curse of agony and 3 points into SM:
Rank 3 Agony : 324+(324*.06)+(324*.06)= 362. However as seen in the screenshot the tooltip only shows 348 at best.
Please fix!
