The WIPComponentDemands file loaded is not showing up in the staging table

The WIPComponentDemands file loaded through Load Planning from Data Files is not showing up in the staging table. We are zipping both the WorkOrderSupplies and WIPComponentDemands files, but only the WO file is being loaded.
We tested the WIPComponentDemands data by copying it into another working file, and it loaded successfully. The client is sending the files directly from two different systems: one for Discrete and one for OPM. The WIPComponentDemands file extracted from the OPM system is currently causing the issue, while the same data loads successfully when placed in the Discrete WIPComponentDemands file.

Attached screenshot in which "WorkOrderSupplies.csv" is only getting picked up in staging table.
