Yup: I can reproduce it too. Toggling the table coordinates inserts
overlays and apparently something is out of sync and that particular
overlay does not get deleted appropriately.

You can check that there is an overlay there by placing the cursor
right after it and evaluating

     (overlay-at (point))

which should return a list of overlays at point. Assuming that you
get a non-nil result with just that one overlay in the list, you can
delete it with

     (delete-overlay (car (overlay-at (point))))

Haven't figured out why it gets left over though.
