the duplicate attributes drop down is from tpl_modules_attributes.php

I still got to troubleshoot it. looks like the settings on line 17 is in it twice (its also on line 46ish.) Could be the problem but I am not at home to test it.

Ajax is not enabled for the dynamic drop down. Just the admin page settings.

Thanks for the SQL fix. can't believe it was one darn word that was messing me up! LOL
