"#% increased Life Regeneration Rate during Effect of any Life Flask" not working correctly

#% increased Life Regeneration rate during Effect of any Life Flask:

{Succour}
Normal Life Flask: not working
Blood of the Warrior: not working

{Ulaman Desecration (Belt)}
Normal Life Flask: working
Blood of the Warrior: not working

I tested each piecemeal while having missing life and observing the changes to the character screen. None of the life flasks used had instantaneous life regain.

Giving this a bump. Found a good Blood of the Warrior on the ground, then dedicated 5 div to a belt craft only to see this not work. The regen numbers don't increase in the character profile and no additional life regen is seen in combat. I sincerely hope this gets addressed.
