CMS Subnav acting strangely on a per article basis
 

<div>Very odd behavior going on here. I can't for the life of me figure it out.

I have 6 articles in a section. Same exact settings on all articles. I select the first one (manual order set) and the subnav looks as expected. Select another and it disappears, another and it may appear again. Now if I go in and edit the articles that do work and save - after saving the subnav disappears. Then I added a new article and the subnav doesn't appear there either now.

I've created a new master style with no modifications and it still happens. I have no mods installed on the test environment either. I've cleared CMS cache and verified and repaired node table.

First article code
<div class="bbcode_container"> Code:

<ul id="navtabs" class="navtabs floatcontainer">
<li class="selected">
Home

• Home
  
• The Basics
  
• Key Elements
  
• Reviews
  

Subsequent article codes
Code:

<ul id="navtabs" class="navtabs floatcontainer">
<li class="selected">
Home

• 
  

Any other suggestions?
