Why are there red polygons on my image? I didn’t do this.

As soon as you open a file, the editor will try to detect panel polygons automatically. This is so that users can start annotating all the other elements as parts of the panel in which they appear. The hierarchy of annotations should always be panels –> everything else.

But what if they are wrong?

You can delete any polygon by clicking on the selection tool to the left, then right-click on the polygon, then click on “remove selected object.”
