[Problem] Generate PDF File with Start Expression

[maxmaxmax222]

Hi all,

Left picture is my google docs template and as higlighted in red is my child table within it (Related Delivery Order). When I generate PDF file, the row is create depending on delivery order I have but unfortunately, the row that is generate from the child table push my signature, comment data to be over the page as shown in right picture.

Any solution to fix the row from child table so it stay within the page? 

Thank you all
