Cut list length not evaluating after custom properties added to weldment profile.

I'm having a difficult time with the weldment cut lists not evaluating lengths properly. This function was working perfectly fine but when I added custom properties to the library feature part (description and material), the length stopped evaluating in the cut lists. Now for length, It evaluates to "LENGTH@@@Partname<as welded>@@@DESCRIPTION<1>@Part1.SLDPRT". When I delete any custom properties, the lengths evaluate again. I've tried unselecting "Update Cutlist Automatically", then deleting the cut list, and finally reselecting "Update Cutlist Automatically" to recalculate the cultist properties and that didn't solve the issue either.

I've searched high and low to find the answer and have had no luck. How do I get my weldments to show my custom properties Ie. Description, material, cost, weight and still evaluate the length correctly?
