thanks for reaching out. I have investigated locally and I am unable to recreate the symptoms. That leads me to the suspicion that some configuration step is missing on your side. There are several questions I have in mind. Whether you are generating reports through a GUI interface or from ISPF. In the first scenario, a missing STEP 16 under TRCUST would cause the DATALLOC job not to be updated and could cause such behavior.
However, the best solution is to open a support ticket (please visit https://support.broadcom.com/) for CA MAT and I will have my L2 engineers investigate your symptoms more closely as well as the current environment setup.
Hope to resolve this bummer soon.
