Yes, I had the same issue, but only with book number 1. With the 4 other books I didn't have any issues because a bookbinder gave me some advise. I'll try to describe it as well as possible. Bear in mind that English is not my mother tongue. The info I got from the bookbinder is something I do now for every book I just bought. here are the steps: 1. place book on its spine, where the pages are binded. 2. open the front cover and and go with your finger over the bind to smooth the cover/page down. 3. do the the same with the back cover 4. now take a few pages at the front and again run over the bind with your finger to smooth down the bind while keeping the other pages at an angle of 45°. 5. take a few pages at the back and to the same 6. repeat step 4 & 5 until you went through the whole book. This is what I did with the 4 other books and didn't encounter the same issue as with the first book. Here a picture which describes the process: here
