Dimmer Switch Load Issue

[C4 Novice]

Hi all, I have just wired a C4-DM201-Z dimmer switch at my home to use with LED dimmable down lights. I have wired it as per diagram 1 in the installation manual but when I power up, the down lights do not completely switch off. The switch says it is at 0% but the down lights are still on (at around 10%). All other functionality is working fine - just can't get the lights to turn off completely! It has been driving me mental for the last few hours. Any ideas or clues as to what could be wrong? Cheers.

The issue is dimmers always have a bit of power moving through them. leds with low wattage will turn on due to this. you need to add higher voltage leds or switch to an  APD dimmer
