Grade Step Progression process showing many errors in Review Proposed Prog. and Salary Updates page

Hello experts,

we are running Grade Step Progression daily to capture those employees that will progress on their anniversary date.

But when you go to Review Proposed Progression and Salary Updates page, we can see that there are many errors from the Run Grade Step Progression process which we think is expected since there are almost 680 employees that this process is running for, and only some of them are progressing daily.

is this an expected behaviour? Or do you have any way how to explain it properly?

This is causing some argument from their side since it's not that great to see many errors in the process.
