issues displaying information in pa20/pa30/pa40

Hi,

I noticed this issue yesterday that Employee information is not showing in PA30/PA20/PA40.

I don't know what that area is called. This area contained fields like: first name, last name, grade, assignment…

I can't find any way to fix it. Please help.

I insert the screenshot below.

Before the issue, the red rectangle was containing the fields named previously.

Thanks,

Sophia
