I had trouble putting in a 6NA and RD-RD to replace a 3-way conventional, and I wondered if anyone could help me figure out how to resolve it. There are two lamps with dimmable LEDs connected through Lutron's "receptacle for dimming". Here's a video of the flashing.

I hooked the Lutron modules up with the blue screw to the red wires and got the result you see. I thought I did it wrong and reversed the top two wires and got no power.
What did I do wrong? Thanks!
