Shown as supported device yet does not show up in the Devices Tab

I have the Dark Project KD87A Fuji version (DPO87_Fuji_ISO_DE ), which is shown as a supported keyboard yet doesn’t show up in SignalRGB. Any help or pointers on how this issue can be resolved? Could the reason behind this be that this model is the same model with different keycaps, yet I don’t believe the software would be any different?

Thank you in advance,
