Fibaro dimmers wiring question (UK)

Hello following the invaluable help from Robin I installed a test Fibaro dimmer with load module this morning, installed at the switch as per the drawing from Vesternet with live wire to L on dimmer, common from switch to SX on dimmer, L1 from switch to S1 on dimmer, a loop from N on dimmer to the arrow through the sine wave on the dimmer and the switch wire to the light fitting also to that terminal on the dimmer. At the light fitting I have the module across the live and neutral.
The LED lamp is still flashing, can anyone see if I have done anything wrong or suggest a fix?

Many thanksUploading…
