How to get rid of these "boxes" in the document?

How do I get rid of these boxes from the Document? I don’t suspect this is a bug or any issue with the app as such. Some setting somewhere I have to toggle and off.
Sorry, I’m not a pro Word user either. Always used MS Word for resume and have been exclusively using a Linux PC and this


was one issue I wasn’t counting on.

I’m using this document to compose a resume. However after saving it and reopening it a later time. It shows up with these boxes. This has never come up in MS Word. What am I missing here?

I’m using Only Office in Linux Mint (22.1). Installed it from .deb (version 8.3.0.97).

Hello @ofcbear7,
Please provide the original file with the boxes for initial analysis
