Hi John,
The new lines come from either (a) the textarea custom field in WP admin Edit Page, or (b) added from WPAllImport custom fields (where contacts are imported from a CSV file):

I am not trying to put new lines on a front-end page anywhere. It is the back-end Edit Page where I want them converted to new lines inside the textarea for editing (first screenshot).
Thank you.
