Query: Manufacturer Defect

After unboxing these shelves, I noticed two holes underneath the plastic wrapping that's on the shelves. (see picture) The holes are in the exact same place on both pieces which leads me to believe there's some kind of defect in the manufacturing process. Other than that, they seem pretty sturdy, and came with instructions to install the shelves on the wall.
