Problem with lookup page in a field

Hi everyone,

I have a problem with a field in a page.
When I press the lookup arrow of the field, I get the lookup page with only the primary key field.
I am joining a image to show what I get.

I noticed that when I press the Advanced button, the page shows correctly…
I need to show more fields in the lookup page but I don’t know how…

Can anyone help me how to do that?

Do you mean this?
