Two or three people have said that they unintentionally selected the wrong version when they placed their order and did not catch the mistake until they received their book. Because of that, I decided to add one more notice on the order page to help avert future errors. There were already three places on each page stating the version, but the new fourth notice is in extra large print that is very hard to overlook.
A few people (three or four) have said that they ordered the full version, but received the family friendly version instead. I suggested contacting Blurb support to resolve any mistakes, but I also did contact Blurb support by email to see what they had to say about the possibility of an error. Here is their reply:

Thanks for contacting Blurb with your concern.
Both books in your account are a different file from one another. You are correct in saying that books are printed as they are ordered, and usually book files are not "mixed" up. In this case I believe the customers ordered one book thinking it as another. The only way to troubleshoot this is having them contact us , that way we can check on our end which file their book was printed from.
I hope this helps. Please let me know if you have additional questions.

So, if anyone is certain that they received the wrong version and wishes to exchange it, contact Blurb and they can check their records to see what was ordered.
The two versions were uploaded to Blurb on different days and have different item numbers. The process is mostly automated so it seems that the most likely point where an error would occur is where a human is involved in boxing the books for shipment. If the invoice has the version that you received then I suspect that an error was made when placing the order.
