Battery monitor setting reverts to its default parameters

Hi guys, my first post here
Recently I’m having a bit of issue with mission planner
I configured the battery monitor recently, it worked fine, alarms and everything
But after changing my threshold for voltage alarm, the setting reverts to its default parameters and voltage is shown as zero and my battery capacity keeps resetting to zero too. I wonder what is the problem, my searches couldn’t find anything related, I hoped you guys can help

please post the settings you are using.
