Template not working in New Blog Templates

This is a prosite environment. The default template is working, but not the premium template, which is configured to work with the premium plugins offered. I understand that the plugin was not created with the ability to have a template "upgrade" within prosites (bummer), but rather is only able to provide templates upon a new blog creation. But when creating a new blog and selecting the premium template, I get a blog created that is using the twenty fourteen theme, rather than the custom twenty thirteen theme I've designed for it. The default custom twenty thirteen template is working fine with the free accounts. Are there any known incompatibilities with prosites? I'm using pretty much all wpmudev plugins.
