Do not showing columns on page

hello I need your help. so I have a table (Customer Agreement) with page (Customer Agreements).
when I’m running the page, two columns do not appear (Balance to Date) and (Balance to Date (LCY)),
I’m sure property “Visible” is on True, it has nothing in C/AL side. even when I right click on the page and choosing the option “Choose columns”, those 2 fields are not there. Any idea why is that happening? Thank you in Advance <3

Maybe the application area set wrong?
