This could be a strike through or a lamination that feel off. There is a similar anomaly on the right wheat stalk.
I think the issue on the Reverse could be a Lamination that De-laminated and folded upwards. It looks like it is hanging on.
I think you are correct. I looked at it under a more powerful microscope (one that will not take photographs) and I can see where the lamination terminates. The issue on the wheat stalk looks like a hit from something - PMD.
