Workflow option under create menu in sites.html is missing

Hi,

As part of migrating from 6.3 to 6.5, I have restructured the workflow and the path is now changed from /etc/workflow/models --> /conf/global/settings/workflow/models. After doing this change, I removed the old path from repository and noticed that the workflow option under create menu in sites.html is missing. Now I am unable to trigger the workflow from sites.html.

It is showing up if I am retaining the old path's folder structure. The workflows are working fine after the restructure. Is it expected behavior since we have removed the old path? Is there any way to fix the issue?
