Resolution

Customer solved the problem by setting DYNAMT=ON and received the proper assignment.

Able to run in another partition without a problem and were planning to IPL this evening to fix the problem when I was able to reproduce the problem in our sandbox VSE by simply setting DYNAMT=OFF in the partition.

By setting DYNAMT=ON back on again we received the proper assignment. So somewhere in our production VSE system DYNAMT=OFF was issued in our F9 partition.
