Word 2016 to PDF conversion inaccurate

User is encountering issue where converted PDF has some discrepencies. very close look at the original word document I found that justified alignment was used, all text appears on a single line in the word document, but on the converted PDF its expanded to a second line. This is the root cause of the issue they noted that text at the bottom of the first page is pushed to the top of the second page.

I have absolutely no clue how/why this happens on conversion. it only appears to affeect this specific line. format is changed throughout the document from left aligned to justified to right aligned depending on the specific information.

I asked the user to ensure the formatting is consistent to see if this affects how the conversion ends up looking.

software is Adobe Pro 2020, using the convert to PDF button added by the Adobe software.

original:

 converted:

note from the end user, she chose to save as PDF rather than use the toolbar option to convert and the formatting is fine. does the save as option use the same converter as Adobe Pro tool? or is it just using the microsoft conversion?
