I am in the process of upgrading a DXA 1.8 CM to DXA 2.0. I have ensured that my Page Template is using the new DXA 2.0 **Generate DXA R2 Page Model** TBB. I am getting errors when publishing/previewing as follows:

> (80040200) An error occurred while rendering Page 'Home'
> (tcm:56-1409-64) No items found for WebDAV URL(s):
> /webdav/MyPub/Home/_System/include/header.tpg.

I dont have an include page with title **header** in my implementation, so I am not sure where this is coming from? ... and why is it bothering with Includes when publishing the page anyway - the whole point of these is that they are separate from page publishing.
