Nanokontrol2 template - error in luma cutoff layer1?

Dear fellow foronauts,
Since a few days I am digging into creating visuals to my music (I am performing mainly improvised electro-trance-jazz-funk ;).
I have come across an error in the nanokontrol2 example template within VDMX6. Could someone check if it is really there or was it a failure at my side:
In Layer1 FX Contr. - Layer mask, the mask image is set to "Layer 3 " instead to “none”?

Cheers, roe.
