Role-based blocks not displaying on non-secure pages

My site is set to make some pages secure and some not. I've got a block set to display only to authenticated users on every page. If you are logged in as an authenticated user the block only shows on secure pages. This is what happens:

• navigate from a secure page to a secure page = block displays on both pages
• navigate from a secure page to a non-secure page = block disappears
• navigate from a non-secure page to a secure page = block reappears

This should not be happening. I would like the block to appear on every page regardless of whether it's secure or not. WHERE is it in the settings of Secure Pages that says "show blocks for authenticated users only on secure pages"??
