Out of the blue, lightburn not recognizing items on screen

I am trying to use the camera to align files on a piece of material. This was going perfectly earlier today. I saw the Christopher Walken post on facebook and decided to give ti a try. Well, it chose its own random place on the bed to start engraving so i had to stop and abort the job. Now for some reason any images on the screen will not trace or engrave in their location. Every file defaults to the lower right corner of the bed. I don’t believe i have changed anything… Help please.

The fix was enabling Absolute Coordinates.
