VRM incorrect System Overview and Consumption data

I have recently put together a system consisting of two Multiplus 2 x120V types for power assist functions in an RV.

​When reviewing the System Overview and Consumption data it seems like VRM is not accounting for 2 inverters powering the system essentially halfling the power consumption in the graph and reporting this as “To Battery” instead.

Having reviewed the Advanced graphs, the “To Battery” isn’t correct as the batteries are 100% charged and in float for extended times. I also deleted the installation from VRM and re-added while away from the RV to capture the data while minimal power was being consumed.
Here are some screenshots of the System Overview, Consumption, Share/Grid as well as Advanced graphs. The Consumption more of less haft what it should be considering the batteries are fully charged. The system is then reporting this “extra” as To Battery" under the Shore view. Advanced graphs show the amps usage of the batteries as well as the state being in Float the entire time.

Your intention for “put together” is a parallel configuration to double the currents or a 2 phase 180 deg configuration to double the AC voltage?
Did you setup the connected devices using the Victron (Quick) Bus configuration utitlity?

The inverters are setup in parallel (master + slave) and operating normally. The Shore/Grid input comes only from L1 (limited to 24 amps) and output is handled by the inverters with both L1 and L2 offering 120v. The inverters split the L1 feed to both output legs and power assist as needed on both legs depending on the RVs demand.

All of the above is working 100% correctly from a operational standpoint. The issue I see is only with the VRM and how it is interpreting the data it is receiving from the Cerbo GX.
