Blinking leds VMBDME

After installing a VMBDME to dim LEDs they flash every 1.5 seconds for a moment. The switches are set to
3 - 2
0 - F
I have an identical result by 220V transformer with three individual LEDs and a LED strip
On the transformer(s) there is no information regarding inductive / resistive / capacitive load.
What are the institutions to prevent flashing and is flashing normal?
thanks for your reply

It depend on the type of the led spots, some are flashing others don’t.
We have good result with the Philips Master LEDspot MV 6W (order code 210733)
