Node title is missing in <title> tag

Hi to all

Currently i am using drupal 7.15, panels, metatags and Exclude node title model. What happen is when i select panel node in admin/config/content/exclude_node_title for exclude node title, automaticly exclude node title in tag also...

Pls install following module

1. Panels(7.x-3.3)
2. Metatags (7.x-1.0-alpha8)
3. Exclude node title(7.x-1.5)

Steps to reproduce

• Create a panel node
• Give any tile (example: node tile = sample)
• Save it and view this node
• You can see inside <title> tag having = 'sample | Site name'
• Now go to admin/config/content/exclude_node_title
• check panels nodes with option ['All nodes']
• then go any panel node view page, now u can see the <title> tag having only =' | Site name'

Pls check
