email notification keeps repeating

[tech4life]

Can anyone help me get the notification to stop repeating. The disable box is checked and there is no way to uncheck it, its driving me crazy. I have 4 active and busy email accounts so you can imagine how the constant sounds are VERY annoying ( I have tried other options i.e. vibrate but I really do need to know when a message comes in for work purposes). I am using the most recent telus stock rom, prior rom did not have this problem.
