VRM Min/Max BMS Cell Voltage intermittent

I've noticed my CAN connected Battery Min/Max Cell voltages are intermittent on VRM. Checking locally with Modbus my readings return with every poll but it seems VRM either doesn't receive the values or it goes missing somewhere in processing. All other variables on my portal are 100%

Attached some data from VRM:

And from my local poller running for the last +-10 minutes:

This is a follow up on the post below and it's when I noticed my data not being displayed correctly.

I tracked down some more data to try and give the guys a better chance to replicate this. When I change my ESS Mode to Optimise with BatteryLife and set my Min SOC to 95% the battery discharges from 100% down to 95% At this point the discharge is blocked and while my PV Charger is not active currently it stays at 95% but the voltage readings become 'discontiguous'. See below.

Once I set my GX back to Keep batteries charged it charges up to 100% and the readings are displayed without any dropouts.

@Teun Lassche (Victron Energy Staff) Perhaps your magic touch can check why this is seen? PS. I don't usually tag Victron Staff in a post so please forgive this one.
