4 relays with tasmota switching every start up

Hello All

I am using this device: AC/DC Power Supply ESP8266 WIFI Four-Way Relay Module ESP-12F Developm – diymore

to automate my two blinds (same room) where I intend to use 2 relays for open/close blind 1 and other 2 relays to open/close blind 2.
The issue for now: every time I have a power outage the board starts up making a very fast on/off only on relay1. I am afraid this could damage the motor when that happens.
I am using tasmota on it

Any guess?
