2 MPPTs but only one showing on VRM

Sorry for the basic question that I'm sure has been answered before but I can't find the answer.

I have just added a second 450/100 MPPT Smart Solar to my system, which also has a Cerbo GX and Multiplus II. So I now have 2 identical MPPTs on the system.

I have series linked the MPPTs together with a network cable. The Cerbo GX and new MPPT have the spare RJ45 sockets blanked off with the RJ45 terminators supplied. But I can still only see the original MPPT on VRM and subsequently the Remote Console.

All are working fine together, charging and talking to each other as far as I can see from the displays and I can view both the MPPTs in Victron Connect. However the VRM is only showing me the charge data for the original MPPT not both so although, for example, we are actually generating 6kw per hour the VRM is showing 3kw.

Can someone please tell me what I have missed? I think I have gone through all the settings in Victron Connect for both MPPTs but I can't find what I'm missing
