Top Navigation in Sharepoint 2010 shows pages even when "Show Pages" option is off

I have a site that is showing the pages in the top-level navigation where none of my other sites are doing this. I saw that the "Show Pages" was grayed out in the settings, so I tried the following to fix the problem:

• Turned on publishing on top level site then unchecked "Show Pages" - NO EFFECT
• Turned on publishing on site with the issue and unchecked "Show Pages" - NO EFFECT

Basically, I cannot hide the pages in the top navigation... what am I missing?
