It is a standard behavior within NetSuite for this preference to not work when using an Advanced PDF/HTML Template, because the adjustments that should be made within the template’s code.
A workaround for this is to adjust the “top” style to every table that is being printed using the Advanced PDF template.
Navigate to Customization > Forms > Advanced PDF/HTML Templates
Click Customize/Edit on your desired template
Look for the line of code you wish to adjust
See sample code:
<table style=”top:15px”>
Note: You can either reduce to shift up or increase the value of top to shift down
Once done, click Save
