Mass and CoG of beam elements

Hypermesh 2017.2

Cbeam elements do not have mass when calculated in hypermesh>tools>mass calc or post>summary>ctr_of_gravity.

But when running in optistruct it does have the mass as expected.

I wanted to check the CoG of my model but for the Cbeam elements there is no mass until I solve the model.

Is there something wrong with the model or is it a glitch?
