Vendor not saved when editing Asset for 1st time.

Vendor not saved when editing Asset for 1st time.

When editing an assest (license in this case) I specify a Vendor, at the price, dates, workstation and workstation name and click update. When I view the asset details again, the vendor has not saved. If I specify the vendor again and click Update it seems to be keep it.

Using Version : 4.1.0
Build Number : 4104

Regards.
