I am sorry for the inconvenience.
Unfortunately you cannot avoid trial versions being shown in our Control Panel - it is limitation on our side.
Currently our expiration reminders appear 60 days before and 60 days after every purchased product license expiration date (expiration reminders regard purchased products only). I've just looked in your products and it seems that the reminder you get is for your KENDO DataViz Commercial which expired on 30-Dec-2012.
Thank you for the feedback. I have logged your ideas (for improving the notifications and the Control Panel forum) in our product backlog.
Please do not hesitate to contact us again for further assistance.
