Hi William,
Please try switch to wordpress default theme, check if the content template does take effect.
If it does take effect, please contact your theme author for what is the function name which for render the content.
and goto your WP admin side, Views-> Settings, in section "Theme support for Content Templates", enter the function name,
Content Templates modify the content when called from the_content function. Some themes don't use the_content function but define their own function.
Also you can try enbale the option " Enable debugging and go to a page that should display a Content Template and Views will display the call function name." to check the function name.
