This is a non-ghosting issue in my experience.
I'm not certain but to my understanding because LEDs require so much less to light, the voltage can leak over to them when a solenoid fires. With incandescents it didn't matter, but with LEDs it becomes an issue as you now see.
To solve it they usually have some resistor or something built into the LED bulb.
This is my understanding of it, so anyone can correct me I'm wrong.
