On the far right are all of the drawing tools. Scroll all the way to the bottom end of them and look to see if a symbol that looks a lot like the thing you drew, a circle with a square around it, is selected. If so, you are in object drawing mode (the top of the Properties panel indicates "Drawing object" which would make it seem to be so). Deselect that and see if that helps.
If you can't scroll to the bottom of the tool, drag the left edge of the tools to make the palette wider, then you should see two columns of tools, and can easily get to the one for Object mode.
