Using Post 2 Post v 1.3.1, I have four of the same type of CPT connected to a page.
When I query these in my template file, I get four results, but the first result displayed is a repeat of the last post in the group of four. (I'm using the default sort order - that is, the way they appear in the Connections meta box on Edit Page)
Put another way, the first of my four connections never appears - but the last of the four gets repeat at the beginning.
The results that do display are all correct, including calls to Custom Fields.
See the query here http://pastebin.com/9JJBEAWR
