Inconsistent Weight of MITRE BENDS - brwei = 0kg issue

Hello all, I have an urgent problem I need help with. 

I have set up Mitre Bends in Paragon E3D with NCUTS -1, no geometry and weight parameter set up in kg/m. In the specification, I assigned a TUBD Component reference. 

The issue is; while my branch brwei seems to be correct, the mitre bends themselves evaluate brwei to 0 kg. Due to this, the weight of spools displayed in spooldrawings differs.

If anyone encountered and solved this issue; I would be most grateful for help! 

Here are brwei and gwei values of a test pipe: 


Brwei of Spldrg (same results if I select spool)

My Mitre bend in Paragon: 

NOTE: i tested this with WEIG as parameter 5 and got same results:

Spec: 

TUBD:

EDIT: 

Might be useful to know; I have set up some pulled bends for bendmachine in a similar fashion, using the same WEIG formula and TUBD element, and they work fine.
