Text box fields place in comment area desapears after upgrade of ofice365

Dear all,

In all my word document, I have different comments inserted at different place. In addition to adding comment to the comment margin area, I was also manually adding Text box in this comment area to add my own note as seen in picture below :

In picture above, you can see my Text box hilighted in red in the comment section that I have added using the fix position option.

Yesterday, an office365 update has been run automatically on my MAC BOOK AIR and now when I open the same document, my text box are not anymore visible when I show my comment section and seems that all my text box goes to the back and I cannot anymore grab them.

On few of then I can just see the text box left ankor which allow me to move back the text in the page area of my document.

But for most of them, I am not able to grab them anymore.

What is the way on my MAC BOOK AIR, to get back my textbox in the comment section or a way to get them visible ?

Thanks for help

regards
