DMX lighting not dimming

Hi! I’ve just learnt how to use Unreal Engine & the DMX plugin but I’ve run into an issue in the sequencer.

When I dim the lights, part of them stays lit up? I’ll attach screenshots to better explain what I mean.

Screenshot 1 is with the dimmer on 0.001

And 2 is moving up to 1.

The light itself dims fine, but there is still a spotlight cast. How do I fix this? Thanks
