sound settings acting up...

[sn95gt]

Just recently upgraded to the TP2, my TP gave out and was given the free upgrade, and so far this phone has been great. My sound settings is "vibrate and ring" for when I receive a phone call. At work I switch over to vibrate only and switch over to "vibrate and ring" when I'm not at work. Well when I do switch back for reason or another the phone will switch to "ring" only but no vibrate. I have to switch it back a few time until it finally stays. I have tried soft reseting and since I have spb mobile shell on it, I make sure that the settings under the mobile shell and the phone settings are the same.

Anybody have this problem???
