Linestyle not Found

I have what should be a simple question.

We have a new workspace set up in PW. The client provides most information using DGNLBs. 

So, we pathed MS_DGNLIBLIST to <folder path>\*.dgnlib. 

Interestingly, no custom linestyles are being found. We have confirmed the correct path the MS_DGNLIBLIST is showing in MicroStation, but no dice. Things like plot styles show up, but no linestyles. 

I even tried opening the linestyles DGNLIB in a separate session of MicroStation, opening an exported copy on my hard drive. The DGNLIB shows no linestyles. It does indicate that the many lines in it are drawn with whatever linestyle. But the linestyle shows as

NAME (<Not Found>)

DS_Linestyles.dgnlib

The DGNLIB is attached. Any ideas???
