Yeelight doesn't remember state immediately

I have 2 Yeelights. One is the old colour bulb model (grey colour) and one is the white one (1S Colour). I have set to remember default power state for both of them. However if the light is turned off from the app and if I switch off the power and switch it on again the 1S colour will light up but the old one will not.
If I switch off power and wait for 5 seconds and then turn on power then the 1S colour will remember state correctly and keep off. Issue occurs only when the power goes out and comes back within 1-5 seconds. However the old model can immediately turn off regardless of the time.

Is there a fix for this? The 1S is connected to Asia and on latest firmware.
