Worker HDL file is getting failed in lower pod after P2T

While assigning the midyear goals, we found two persons numbers having leading/trialing spaces in the assignment numbers. To fix this we have created HDL. Since, Dev4 and Dev6 refreshed recentl,y we tried loading the HDLs, In Dev6 We were able to load successfully but in Dev4 the same is getting failed with a generic error message: "An error occurred. To review details of the error run the HCM Data Loader Error Analysis Report diagnostic test. Message details: XXXXX Unit is required for Employees.."
The same HDL file was loaded successfully in all other lower pods except in Dev4.
