Why does shelley dimmer on HomeKit shows as not compatible?

Installed a Shelley dimmer 2. installed the native Hubitat download for the Dimmer 2. Toggled the "switch" in the Hubitat dimmer "device" interface. Device appears in HomeKit but in non-functioning. Home app says it is incompatible. Are there any solutions?

Update: After playing with the Hubitat interface I somehow located the "Dimmer" device. It now is working well. Not sure how I found it though. What initially displayed, and is still there, but turned off, is the "button" device. Otherwise still very please with my Hubitat.
