Hi Jeff,
All files including templates on BC are .html based. IF you have .dwt files on there it is because you did not go through the DW BC tool or extension(older DW) and just uploaded them. Delete them - BC does not use them if you have those on the host.
In terms of just directly uploading you need to ensure two things with templates.
1. The folder locally is EXACTLY the same spelling and capitalisation as the host.
2. The html file template HAS TO HAVE {tag_pagecontent} there to be classed as a template.
I think 2 may be your issue?
