Limit Internal Charge to Prioritize Other Energy Sources Ignores BMS Re-bulk

Greetings Victron community,

I've been closely monitoring the performance of the new Multiplus feature that allows limiting internal charge to prioritize other energy sources. However, I've encountered questionable behavior when the Multiplus remains in Sustain mode even as the voltage drops below the sustained value of 13.2V. The BMS is clearly requesting a bulk charge by raising CVL to 14.3V (Charge Voltage Limit).

You can observe this in VRM by filtering for [2023-11-15] between [17:00] and [18:00]. https://vrm.victronenergy.com/installation/177064/share/4bdfba95

I have attached the VRM extract and Multiplus configuration for your reference.

Your insights and guidance on this behavior would be highly appreciated.
