How do I remove Orphaned network license on workstation since it does not allow borrowing of new licenses ?

My SNL manager(licensed for Solidworks Premium 2012) shows no licenses borrowed.
My Win7-64b workstation user shows license usage status as none. Same as the License Server.
However under the Borrowing License Tab, the user seess a license for Standard and a License for Premium borrowed and for a date in mid April,
when in fact the date is late April, over a week later.

The date and time on the SNL server and the date and time on the PC are the same !!!
