Issue drawing on a Google Maps image

I am having trouble drawing over top a Google Map image that I imported using SketchUp’s feature. When I draw on the image now, I can’t see my lines or protractors until I stop clicking. I was able to draw over top the image last night. I’m trying to outline some buildings for a group project to get rough dimensions. Has anyone else had this issue before or knows how to remedy this? Thanks in advance for any help that anyone can provide.
