Retrofit Led Kit for GE Dimmer Switch

I have recently installed a few LED retrofit kit in conjunction with my GE Smart Switches. It seems that the retrofit kit is buzzing and flickering when I try to dim it. They say on the box they are dimmable. Can anyone reccomend a solution?

It could be that the retrofit kit is incompatible with the GE switch but it may be more likely that the switch is incompatible with the LEDs.

When did you get the switch? The older GE smart switch models could only handle incandescent and dimmable CLF

I just recently bought them and they say on the box they are LED compatible.
