AutoNotification Questions about Blocking

I create a profile to intercept a text messaging with a specific title. My entry task is Block then create a new notification. However, I noticed a few things I dont understand:
1. The text message I am trying to block still shows a pop up notification. I thought Blocking would prevent this?
2. After a second or two, the notification is dismissed and then the Autonotification I set up is executed twice! In other words, I get 2 new, identical notifications. Is this because my phone is actually created 2 notifications (the popup, then the normal one in the notification shade)? How do I block both and dont have it trigger my entry task twice?
Here is my Profile
Intercept, only on created notifications, notification title matching "xxxx"
Here is my entry Task
A1. AN Block
A2. Autonotification

 

I am not sure I understand.. What do you mean set blocks in the main app? Are you saying to just create a Block task, do not associate it with a profile, then just run it once manually?
Also, do you have any input on my questions about the pop up notification and regular notification for my text message? How do I keep 2 new AN notifications being made for every text message?
I know I could probably set a variable to true the first time the entry task is executed and then check for it before executing it again but I was wondering if there was an easier way.

 

Yes, I made sure I am only triggering on creation. I am fairly certain the profile is counting the pop up notification and the regular notification in the bar as 2 separate notifications which is why its executing the entry task twice as well. It would nice if AN could know that the pop up and notification bar are the same and just execute the entry task once. Perhaps capture the notification id and if it occurs again with X seconds ignore?

 

Not sure what happened but the double notification went away. I went into AN settings and turned on the Update option. Of course this led to a Tasker error because there was no notification to update. I then turned off the Update option and now I am not getting two notifications anymore.
