More notifications than listed


I get notifications but they don't add up. I get 30 listed after I delete and reinstall but but the number actually shown is 200. Could you please tell me does your notification service add up all notifications and only show the 1 notification for a stock even though a stock may be listed in more than one portfolio? 

I hope I explained it right but please let me know.

Thanks so much.
