I have edited a non-fiction books for months. LO saved me when MW decimated my manuscript. A lot of detailed work but I was very relived. Each month is marked; and for months all was well, saving, and returning. I was almost finished editing. Then this morning, Oct’s file and its 749 footnotes, changed from 10pt to 14pt. (As well as Septembers), and I can’t figure out how to make a default format and change them back.
On closer review the page’s formatting has changed to center from full.
