Perfection of Soul (Staff Mastery) gives 2 stacks

[Replacement]

Endurance discount buffs from Tanker > Staff Mastery > Form of the Soul (Perfection of Soul buff) are occasionally stacking, but it's weird.

First I see this:

Then It moves up to this:

 

But sometimes it'll drop to a single stack and give me the single stack's overall total.

 

But I usually end up at level 3 with this weird math:

 

Occasionally I get the same overall total but only a single buff instance listing:

 

No issue with the other 2 Forms with their Recharge and Damage buffs -- just the End discount is wonky.

 

EDIT: This was done on the Beta server.  I can confirm if it happens Live tomorrow, but I do't think anything's changed for Tanker>Staff to affect that.
