That's commen that they call for one thing, but acutally require somehting else.
It's not right, but that's just how it is.
If you serach around the posts, you'll find that detailing is a common oncern among the forum.
Yes ad drwn it called for a CJP, but like you found out, only a PJP is required. Get it in writing to cover yourself.
Good Luck
