Master / Detail - Single Record Form Problem

Hi

I have the problem that when I create a form and use the orientation “single record” sometimes a field is not displayed, while using the orientation “editable grid (view)” itself shows, this is the second occasion that gives me this problem.

Pic 1: Asuming a select “56101”

Pic 2: Single record - Don’t appear

Pic 3: Editable Grid - Appear

Thanks & regards
