source IP not extracted using TA-Windows-Exchange-IIS

Hi,

I deployed the Exchange Addon TA-Windows-Exchange-IIS in our exchange servers and I confirm that I see IIS events coming in.

The problem is that the events have two different IPs , one at the beginning of each line corresponds to our exchange servers and the second (at the end of the line), that often corresponds to public IP address of the remote clients. Unfortunately the field extraction of the addon only takes the first IP.

Is there anything that I might be missing? I can see that there is an additional addon for IIS in splunkbase. Is it better to use this instead? 
we are using Exchange 2016.

Thanks a lot
