When plywood is made and rolled into sheets and glued, a few "straps" of the
paneling gets "glued to the sheet. Some of these get ripped off leaving a
laminate showing.....or glue.......Some of the strips stay on.........in
either case this is not a problem. You can check by walking upstairs also
to see if there is any give inbetween the bays......more likely not.
If it were the case a person could block any of the suspect areas.......
no worry's
