IT looks like (Based on GBO layer) that you grabbed and placed a component, but because of the selection filter settings you had set, your component was placed on the PCB but the silkscreen for the component stayed where it was on the workspace. That is why it complained that the film size was too small and why you've made it so large to get it visible. I'd personally change the settings so that the pcb layers were all referenced to the absolute origin, or, maybe an inch or so offset from the absolute origin for accurate placement generation. And, zoom in on your "mystery" component silkscreen - you should be able to figure out which part it is, change your select filter to GBO layer and move it next to the correct part.
