STEVAL32G4 - False Over Current at Startup if Drive Protection is Enabled

I am having false Over Current conditions when the inverter board starts up, before any kind of operation.
Motor Pilot shows Over Current fault that happened but FAULT_OVER, most likely a short condition that prevents further operation without acknowledge. Once fault is cleared everything seems to be working normal.


In MC Workbench I have increased Digital Filter Duration to 1.51ms in both Drive Protection and Over Current Protection tabs.

Testing is done without any motor connected to the board.

Anyone having similar problems? Is this reproducible on other boards?
