It took me a while to find the extra leaves, but they’re underneath the big leaf on the left side (one on each circled quarter).

This is, hopefully, a picture of the “down leaf” error. Look to the left of the ear or corn. See the leaf that droops over. Under that droop is an “extra” leaf.
There is an 'up leaf" error, in the same spot. Extra line.
