Multiple Instances and AlwaysOn Availability Groups

Hello every one,

In my scenario, I have two servers in each of them two SQL server instances

(Server 1: Instance 1 and Instance 2, Server 2: Instance 1 and Instance 2)

I created an always on groups between the instances like this: 

     - Instance 1 from Server 1 with Instance 1 from server 2 : AlwaysOn Group 1

     - Instance 2 from Server 1 with Instance 2 from server 2 : AlwaysOn Group 2

and I have create a two listeners Listener 1 for : AlwaysOn Group 1, and Listener 2 for : AlwaysOn Group 2

the problem is when I try to connect with the Listener 1, it connects me to the AlwaysOn Group 1, 

but when I'm trying the Listener 2 it also connects me to AlwaysOn Group 1  not to the alwayson group 2 

I did not understand what's wrong with this.

Thank's for help me 

Have a good day.
