Hello snesbit -
I am sorry to hear about the difficulty you've run into with the template selector. We've received a few similar reports and are looking into the cause. However, there is also a different issue occurring at this time relating to posting listings, which our engineers are currently working to resolve. (Please see this thread on the forum for updates regarding that issue).
I will update this thread as soon as there is more information available regarding issues with the template selector. Apologies for any inconvenience this causes.
