Changing "Source Charge Priority" form MQTT doesn't update GUI

[gianfrdp]

I'm integrating SolPipLog with Home Assistant.
From HA I can change "Source Charge Priority" publishing a MQTT message on topic "solpiplog/pip/charge/set".
But when I change inverter configuration from MQTT, corresponding Config on GUI doesn't change, the drop-down box remains on the same value, but on Main tab value changes and Inverter takes new value.
Reloading configuration doesn't update configuration.

Inverter MPPSolar 5048.
