ServiceDeskPLUS MSP , group notification doesn't work

Hi, We recently purchase Service Desk plus MSP, we found notification doesn't send to group technichians after a new ticket created
what we have done is
 
1) configured support group for the accounts. ( see attach two screen copy)
2) enable the notification in the notification rules for the accounts ( see attach two screen copy)
 
The problem is
 
1) when the technician doen't pick up the request, notification never send out
2) when a new ticket assign to the group, notification doesn't send to group technicians
3) when the tickt re-assign from group A to GroupB, group B technical never receive any notification
 
It is very urgent, since we need to use it next Monday.
Please kindly reply ASAP
