Export problem when PSD-File has adjustment layers

Hello, I have problems with exporting to PDF when the PDF file in the AD document hast adjustment layers.

See movie.

any change you can upload the Affinity file?

I would recommend to check if you have partial transparent pixels in the result. to check,

• in Photo: use channels panel, select alpha channel, inspect for any pixels not pure white (info panel will help)
• in Designer: you can use a channel mixer adjustment to map the alpha channel into all RGB channels. inspect visually, or add threshold adjustment to spot any pixels not pure white. 

I see a combination of nested layers, adjustments, and masks which is another potential cause for the issue you are observing.
