KC868-H32B momentary switch self reset

[stybyk]

Hello,
I am facing issue with KC868-H32B relay settings, when i enable relay momentary timer for more than 10 relays, entire settings reset.
Relay setting, password setting all gone. 
Chip module is GD32F103 
Firmware version H32B_V4.37

Any idea what could be the problem ?
