Only getting one "Traffic Item Statistics" when I have multiple traffic items

[assadniang]

Hello,

IxNetwork 9.20 Python3 ixnetwork-restpy==1.1.11

I have a IxNetwork config file with 2 traffic items configured, from the GUI I am able to get the stats from both traffic items in the "Traffic Item Statistics"

With the following code, I am only able to get the "Traffic Item Statistic" from only one traffic item When I print the "Traffic Item Statistics", I only see 1 of the 2 traffic items:

Code:

"""This script demonstrates how to get started with ixnetwork_restpy scripting.

The script demonstrates the following:
    - connect to an IxNetwork test platform, authenticate, add a new session and clear the config
    - create 1 tx port and 1 rx port
    - create traffic from the tx port to the rx port
    - start traffic
    - print statistics
    - stop traffic

Output:

As you can see only 1 traffic item statistic is outputed, while I have 2
