Mortal wounds in aura tracker

[Nomaddc]

Was struggling to make it show up in there on my warr (with rend).
Rend I added with params: target, debuff, spec arms, position 1; and it works just fine.
Mortal wounds (which are incorrectly listed with mortal strike id in auras with stock version) I changed to proper Mortal wounds id (tested with weak auras - works perfect), set same params as for rend except position, which was set to 2. It doesn't show up. Just nope. Any idea how to fix it?
