How to get unbraced length for major and minor axis in RAM DataAccess

For whatever reason the commands to get unbraced beam lengths are returning 0 for any beam I try. Any advice?

I'm trying to print values from IBeam.dUnbracedLengthAxialLX, IBeam.dUnbracedLengthAxialLY, etc.Is there something I'm missing that must be done with the IBeam.lUnbracedLength?

Thanks in advance.
