Removing box around text from google doc comments

I had a doc shared with my collaborators. So I commented my part on the google doc sheet itself. Later when I downloaded the same on Microsoft word I can see all the comments etc on the doc. I can also accept it, but the box/border remains around the text still remains. Even I try to click the No markup option the box still remains there. How do I can remove it

This question wasn't closed despite the comment, so I'll assume it's still open to answer. To remove these boxes from the entire document (and keep the text in them), use Control + A (select all), right-click anywhere, then select "Remove Content Control". You do need to have "Track Changes" off for this to work.
