getting "Trial License has expired." pop up

we are using SEPM to push client upgrades to SEP 12.1.6318.6100

but on few clients, we are getting "Trial License has expired. All content downloads will discontinue on 9/14/2015."

we never had Trial versions of SEP, issue will usually go away after reboot or update policy.

Symantec says its cosmetic, but still annoying and wanted to see if anyone else has seen this.
