LED lights flickering might be due to driver incompatibility between the bulb and dimmer. 

The executive element in the ZEN72 Dimmer switches is TRIAC, a leading edge driver. If your LED bulbs call for a dimmer that uses a trailing edge driver, it could cause the lights in your installation to flicker.

If you'd prefer not to change the bulbs, you can try adding a bypass to the load.

Another important details is to make sure your LED bulbs are labeled as dimmable. On/off LED bulbs are not compatible with dimmers and will not perform correctly. 

Never use a Z-Wave dimmer with smart bulbs unless you disable paddle control on them first. Dimming smart bulbs from a wall dimmer may damage your equipment.
