2.0.68

What game client version, classic or retail, windows or mac and language are you using ?

10.0.2

What steps will reproduce the problem?

1. Create 2 ICON indicators
2. Create the following 'Mine' buffs:
   1. Reversion (366155)  (do NOT track this by spell ID)
   2. Reversion (367364)  this is Echo version   (track this by spell ID)
3. Set Reversion (366155) to show on ICON indicator 1
4. Set Reversion (367364) to show on ICON indicator 2 
5. Cast Echo on self
6. Cast Reversion on self
7. Observe that for a brief moment ICON indicator 1 will show the initial reversion and then a few frames later the Echoed version - overlapping.
   1. You can cancel the buff and the other will show up on Grid2
8. Observe that ICON indicator 2 will show nothing

Workaround: track Reversion (366155) by spell ID as well (so track both explicitly by spell ID). Maybe this is unavoidable with the way Echo works, but it's confusing to be fair.

Working as intended, use spellid tracking if you want to differentiate both debuffs.
