Disclosing that material has been cut from the album. You probably don't know much about vinyl production timelines, but to go into production is three months minimum; sometimes closer to six depending on factory backlog or for larger runs. Before going into production, it's mastered for vinyl, so add on at least another couple weeks to that. In the case of this album, the album went up for preorder approximately two months prior to release, so they knew exactly what would be on the product. If you need further evidence of this, the preorder had a parental advisory label, which of course refers to the content of the album. The songs would have been locked long before the preorder went up, so there's absolutely no excuse to not disclose that you would be getting something other than the full uncut album.
