Problems cutting shapes out - Designer

[richardmtl]

Hi! I have a shape with several pieces that I want to cut out. I have followed the instructions I found here: https://graphicdesign.stackexchange.com/questions/119718/why-cant-subtract-complex-form-in-affinity-designer but it doesn't work. Somehow, I got it to work once with a different file but I'm not quite sure how, and now, I'm unable to reproduce that success with a new file. Is this a bug, or am I missing something? I want to cut out the red shape from the white background. When I cut it, it ends up looking like this, instead of the holes being cut out and showing the transparent background:

 

What am I doing wrong?

You can also use Layer > Create Compound - change the Curves layer to Subtract. You don’t need to change the Fillmode with this method, plus objects remain editable, such as you could rotate the curves layer.

Adding slightly to this, note that alternately you can Alt (Windows) or Option (Mac) click on the toolbar Subtract button to create the compound.

Thank you everyone, that's what I was missing! Works like a charm!
