Haseman 4 channel dimmer based on Fibaro

Hi there,
I recently got several Haseman 4-channel z-wave Fibaro-based dimmers.
When I include it using the app, it appears as “Fibaro RGBW Controller”, but only has one device. I believe it should have four devices or one main device and four child-devices.
Does anyone have advice using this device in SmartThings?

It should be recognized as a “Fibaro 4 channel dimmer”.
