I'm trying to remove the light blue boxes behind word fields in Acrobat pro

Go to Menu (or Edit) - Preferences - Forms and tick off the box next to "Show border hover color for fields".

This will only change how the files are displayed for you, though. It's not a setting of the file itself, so it might appear differently from someone else opening it.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
