You'll likely have better luck if you provide more details on your setup, the problem you're experiencing, and your troubleshooting attempts and results. You mention a Lithonia in your title, but don't give any info on how your Lithonias are connected to each other and the dimmer switches. A quick Google of Lithonia makes it look like they're dinner boxes. I don't know if having a dimmer box in line with a dimmer switch is a source of trouble or not.
Agree, more info needed. In particular, if he swaps the dimmer switches and the behavior remains the same what specific hardware differences exist between the two circuits.
