Boolean Subtract problem in Designer

[CraigK]

I am using the latest Affinity Designer and I am having issues with the Boolean Subtract function. I have a blue rectangle curve at the bottom of my layer stack and fifty white star curves above it. I am trying to subtract the stars from the blue rectangle. When I do the subtract function, the white stars disappear, but show that they are still there, but now part of the blue triangle and have not been cut out.  How can I cut these stars out of that blue triangle? Thanks.

Select the result of the Subtract. Look in the Layer > Fill Mode submenu. If Winding is ticked, click on Alternate. If that doesn't solve the problem, please attach the Affinity document file in its state prior to attempting the Subtract.

Unless you have a particular reason to use Boolean subtraction, an alternative might be to group the stars and clip them to the rectangle:

Or if you are sold on a Boolean subtract, select all the stars, choose Layer-Geometry-Merge Curves (to create a single curve comprising all the stars), then select the blue rectangle as well and then try subtracting:

As long as the rectangle is below all the stars they should subtract. Another option is to select all the stars, then Layer > Geometry > Merges curves

Thanks firstdefence and h_d , but I tried those methods without success. I need these stars to show transparent through the blue rectangle. It's for a garment print file and I need the white to be transparent as the white will not print on a white shirt. anon2's answer provided the solution. Many thanks. Still don't know why the subtract doesn't work like it should though.

Many thanks everyone.

You had me at 'white'...

If you start with a transparent background and white stars then my second suggestion should work:
