NOC View - Max Number Tabs?

I have a NOC view I created a while ago that had ten tabs that cycled through every thirty seconds. I recently added an eleventh tab to the view. When it cycles now, however, it skips the final tab. I've moved the newly created tab to a different place in the rotation, and it consistently skips whichever tab is the eleventh. Is that a limitation to the NOC view, or did I misconfigure something?
