Shaper modifier not working on Crystal belt

My in game submitted report is : 699,396,629

BUG: Apparently the modifier that provides "32% increased Energy Shield from Equipped Body Armour" (shaper mod) is not working.

This is my body armour:

Necrotic Armour
--------
Evasion Rating: 2773 (augmented)
Energy Shield: 569 (augmented)
--------
As shown above the incremented ES from the shaper modifier should provide a flat 182 to my build (569*0.32) but looks like is not working as intended.

Im currently wearing a belt that gives +60 Flat ES as a local modifer and its giving me more ES (+90) than the belt with 32% increased ES from body armour, even when the crusader modifier on the same belt has a higher increased that than one I'm currently wearing.

The item in question has the following stats:


Item Class: Belts
Rarity: Rare
Miracle Harness
Crystal Belt
