Inbuilt free level in Prosite not working for themes

Hi, I set up the prosite level. I only had one paid level. I started a new site on a free level (lernen tarot) to see if it all worked well, but when I went to choose themes only the prosite themes were there. I went to prosite theme settings, and I can only choose pro or none. I added another level called free level, but now my new site says 'you have 30 days left in your FREE free trial, check out how to prevent loosing free features'....how do I get the free themes to show up in the inbuilt free level in prosite..?

Cheers Inger
