Cannot remove text "Gift Wrapping: No" from http://localhost/orderdetails (checkout attribute already deleted)!

Hi,
need help as dont know anymore how to remove the string "Gift Warpping: No" which is visible from http://localhost/orderdetails.
I had already deleted checkout attribute. Also, was try to found the line from solution files. Nothing!

Hi,

this checkout attribute appears on the order details page because the order was completed before you deleted the attribute.

If you want to remove this block from the order detail page go to: Views -> Orders -> Details
and comment out  <div class="section options"> block.

Yeap, correct. Thanks for help.
