In your ODS statements, the stylesheet reference is a location on your "local" machine:
"file:///C:\inetpub\wwwroot\BIClientStyles\AMODefault.css"
And there is no "AMDDefault" ODS style built into SAS, so unless the report viewer can find the CSS file, your style won't be the version you want.
If you use SAS Report format (not HTML) and publish the report to the Report Repository (using EG), EG should fix up that style reference for you.
Otherwise, you might consider placing a copy of the style that you want on a web server, and then changing the stylesheet reference accordingly. Example:
ods html
STYLE=AMODefault STYLESHEET=(URL="http://myserver.mycompany.com/styles/AMODefault.css");
