Problem with flashing bulb in Sanicopolux Smart WiFi double switch

Hello, I have purchased a double switch for the lamp "sanicopolux touch wifi smart switch with capacitor", I have connected it to the existing wiring in place of the old switch. Everything works but the problem is that the bulb on one circuit flashes and so does the warning when the capacitor is not inserted. Where do I connect the capacitor? I am adding a picture of the connection. And it seems to me that I plugged the capacitor behind one of the lamps into the neutral and phase circuit.

You have it exactly drawn (in parallel with the light source/bulb)

Perhaps the one where this capacitor is not present.
I suggest putting in a second capacitor so that these capacitors are on two circuits.

With the capacitor, it also flashes; whether I put it on or not, it flashes.
