How to turn off overlay mode and delete prevous roasts

New here cant figure out how to do this.

I’m not at the roaster so I have to rely on a flakey memory. Either in the lower right corner of the Roast screen (and others) is a grey but visible “Cancel” button (that may be exclusively for Recipes… can’t recall), or in the top ribbon is a button that says “Cancel Overlay”.


I would like to delete some of my roasts from Community Roast World?,or from my Roast activity log can any one help me please.
