Markup Panel appearing with every word document. Comments column now in some weird thing.

Good day,

I am so confused I do not even know how to explain all the issues.

1) Opened a word document today that I closed yesterday.

Opens up with some thing called a Markup Panel.

Go to review and select no markup.

Fine for now, but then appears every time I reopen the document, and all other documents.

2) Up until today, my comments were nicely formatted in a column on the right side of the screen.

Now they are in some thing called a "reviewing panel" which is terribly formatted and located in the wrong place until I drag to to the right side.

Is this something I have caused or some Word Update (God, I hope it is not the latter.)

3) Also, the little indicators next to the lines where the comments are located are no longer present, so the only way I know there is a comment on that line is by clicking on the comment in the stupid "reviewing panel"

How do I get back to what I had yesterday?

Thanks so much for your help.

Dave
