Qubino mini dimmer duration doesnt dim but steps are very visible

Hi,

I use the Qubino mini dimmer on a few lights and when a trigger a flow card dim for 5sec with the duration option on the flow card the steps of the dimming are very visible so it seems like if i dim from 100% to 5% for 5 it doenst fade but just dims 19% every sec.

Does anybody else experience this?
