Problem with e-mail notification when an issue is added to a group

Hey all,

I've encountered a situation as follows:
- account created in SD-MSP ( X@X.X)
- support group Y in the account created
- business rule created (if sent to X@X.X, then place in support group Y)
- when sent, group assigned correctly
- notification rules - when issue created, notify technicians

The problem is - I do not recieve notifications when an issue is created. When it's updated - it's okay.

Now - I went into the group and checked the option notify a group of technicians when an issue is added, but - what I noticed - when I select them and click Save, I get the pop-up that the change was submitted correctly. But when I open the group settings once more, the tick is off.
