Viewing email on my computer doesn't clear it on phone

http://forums.androidcentral.com – If I'm sitting at my computer I usually get the notifications for new emails within a few seconds of each other on my phone and computer. On my nexus when I'd look at a message on my computer it would cancel the notification on my phone. The notification light would stop flashing and I think the icon at the top would go away. On this phone though that doesn't happen. Same if I do it on the phone first. Anyone have any ideas? (HowTos)
