Using Page Composer to make changes to the "Lines" section of Expense Request Aprovals

i'm trying to make a change to the lines section on the expense request aprovals page. Specifically the no receipt field seems to be delivered showing the wrong label so its very confusing for users. I can make any other changes to sections using page composer and they take effect immediately but for some reason any change to the "lines" section does not seem to take effect. I know i'm looking at the correct composition and form factor.
