The document versions are different. Word is an online editing software. When users use it, because the document version is different, the red label turns blue. This kind of problem can be solved by uniformly updating the document version to the latest.

Because the modified format is set to display by author, it can actually be modified. When the computer opens Word, click Review in the toolbar. After entering the review page, click the icon in the lower right corner of the revised version. Click to enter revision options, and then click advanced options.

In the pop-up option box, set the note color to red, and then click OK. After confirmation, you can see that the color of the label has changed from blue to red.

First open the Word program, and then open a document in Word. Then, select the content to annotate. Then, find "Review" at the top of the main interface and click "New Annotation". Then, enter the content in the "Comment Bar". Click "Revision" at the top of the main interface.

You can try setting it in the revision options, where you can set the modified color.
