Problem: Osram Smart+ Flex Rgbw turn Red light after When the electricity returns

A few days ago I installed two kits as per the title. Everything ok but after the power goes out, when it comes back the power fails, the LED strips turn red on its return. Very frustrating, how could I fix it?
I have no idea if osram is the problem, I only have 2 zigbee lights, the rest are switches. I think it is a SmartThings Hub problem.
