We are experiencing this issue as well.

I am seeing this as well

Same here. I assumed it was a product defect.

My guess is they will roll a patch into the new Self Service announced today at JNUC.

Same here.

Yes, I'm also hoping for this to get solved. I also have seen instances where it would say in Self Service that an app failed to install, but in reality the app successfully installed! Not a big deal for me personally but I just don't want our users to be confused!

I am also seeing this.

I was having the same issue...

Delete or rename ~/Library/Application Support/com.jamfsoftware.selfservice.mac/

Log out and log back in.

Phantom notifications gone!

Thanks a lot !

I wrote a little skript for a policy, so people can fix this problem by themselves. 

sudo pkill -f "YourStoreName"
sudo rm -R ~/Library/Application\\ Support/com.jamfsoftware.selfservice.mac/

Thanks for the information. I used:

#!/bin/sh

# get current user
current_user=$(scutil <<< "show State:/Users/ConsoleUser" | awk '/Name :/ && ! /loginwindow/ {print $3}')

# delete com.jamfsoftware.selfservice.mac for current_user
rm -R /Users/$current_user/Library/Application\\ Support/com.jamfsoftware.selfservice.mac

All the best,
