Unknown column 'title_pane' in 'field list' query

Just reinstalled drupal 6 for a clean install. Got latest ver of Ctools 6.x-1.1 and Panels 6.x-3.1
Following http://drupal.org/node/206792 - Panels 3: Creating a new front page with Views -
I came across this error when trying to save at step 49.

* user warning: Unknown column 'title_pane' in 'field list' query: INSERT INTO panels_display (layout, layout_settings, panel_settings, cache, title, hide_title, title_pane) VALUES ('flexible', 'a:0:{}', 'a:0:{}', 'a:0:{}', '', 1, 0) in /var/www/jameshorvath/drupal/includes/common.inc on line 3468.
    * user warning: Unknown column 'title_pane' in 'field list' query: UPDATE panels_display SET title_pane = 11 WHERE did = 0 in /var/www/jameshorvath/drupal/modules/panels/panels.module on line 708.

I hope I'm not painting the devil on the wall, I could be missing something. But it's suspect because I've been creating panels w 6.x-3.0

Note: I reverted back to 6.x-3.0 and no error/warning
