how to remove highlighting in word document

At this point, I could easily have re-created the form from scratch, but this is something I expect I will need to do in the future as well, so am hoping to discover the correct process to remove a highlight on a previously-created form. If I've left anything out that might help, let me know. The document doesn't seem to recognize the highlight as existing, but it certainly shows up in every mode (print, edit, prepare, preview, etc.). The problem now is that I cannot select the highlight itself - it seems to float as background color irrespective of any text, but Acrobat doesn't show any markup, watermark, image or any other type of object as existing in the document.I have no comments in the document zero, zip, so locking doesn't seem to be an issue.

The default option is When selected, which. I mention the timing in case any updates were made to Acrobat in the interim. Scroll down to the Show document content section and select an option from the Field shading drop-down list. After getting a new computer, I opened the form again to continue working on it.

The form is fillable and has a couple of buttons (Submit Form Clear Form).
