While creating New Manage Property, not able to get list columns options in sharepoint 2010?

Question

 I am creating new Manage Property in sharepoint 2010, while assigning it to list column, the list columns are not available in add mapping fields.
 
How i get all list columns in add mapping list?
 
I did full crawl after that not populate into 'select a crawl property' section.
I also find prefix with ows_ but it not there.
 

Any approach would helo lot!
