My Books arrived—With another book's chapter tucked inside!

I was so excited to see a stack of boxes outside my garage. My book is scheduled to release June 9th. Then I flipped through it and found these stories and pictures related to the 3rd Reich in place of 5 of my chapters. I’ve emailed my publisher. Has anyone ever experienced anything like this? I’ve got 300 + books. I haven’t opened all the boxes. It would almost be better is they’re all a mess than some of them so we can start over. P.S. My chapter is on the left side of the photo and someone else’s is on the right side.
