Apologies for the necroposting. I just don't know where to ask this.
Regarding the Yeti palette, both 'periwinkle' and 'shortcake' make my Photoshop (2025) throw an error: "The command "Make" is not currently available".

I chose to stop and look further into what was causing them, and below is exactly what both of them said:
"New: channel
At: mask channel of layer 'Background copy'
Using: mask channel of current layer"

I'm a complete Photoshop rookie and would greatly benefit from some help with this :(
What's going on and how can I fix it?
