Using adjustments to convert to B&W - does not work

[Kvothe 0]

I started using Affinity a couple of weeks ago and in general this is great to work with (I do not do many things with it) - but today I am struggling with a probably very simple problem. I just want to convert a picture into B&W by using the small adjustment button on the right and it always opens a new empty "black and white adjustment" layer - which seems to be empty and with which I just can't do anything.

 

What is wrong with my approach? Any settings wrong?

 

thx for help in advance

Is not clear what's going on from the screenshot.

It seems you are adding a B&W adjustment layer with a mask of the cow, but in the underneath layer, the cow has been cut out?

Anyway, if you want to use the B&W adjustment when you create the adjustment make sure you don't active selections or the adjustment will apply only to what you have selected.

Hope that helps.
