Master pages unwanted rotation
So I have a document that includes a four-page wrap that is 7.5" x 5.5". This document also has an 11"x15" insert (The piece is an instruction manual where the installer can unfold the insert to see the details of the specific install; the wrap just includes boilerplate, covers, warranty and contact info). Previously, I had built these two pieces separately. I tried placing the larger document in the middle of the wrap so I can reduce the number of files I'm creating and sending around for proofs. But when I apply the master pages for the insert pages, it rotates the master elements 180 degrees. When I edit the master page, the elements are correct. The wrap pages continue to work as expected.
Two questions:
- Why are the master page elements rotating?
- What can I do to fix it?
