how to choose page template in EB?

Hi:

Here's my site:

Easy Blogging is working well, except for one thing: when my users create a new Page, the only way for them to choose the right sidebar template is to do it from that page's Quick Edit. Why can't they choose the attribute when they're writing the Page?

Please see my developer's screenshot of the problem.

Perhaps I have something improperly set?

It makes what should be a simple thing more complicated, so I would much appreciate it if there's a fix for this. thanks!
