Multiple Page PDFs only export page 1

[Lord McSquash]

I have been trying to export a .pdf of a 5 page document. I only get page 1. Today I tried to make a .pdf of the last page "Current Page" I got page 1. This didn't happen on last year when I was making lots of .pdfs. 

Running Catalina (long story, downgraded from BigSur), version 1.10.5.

Laptop closed with 2 monitors and Logitech monitors. Added a wireless brother MFC in January. Haz drivers.

Why?

Hi Lord McSquash,

If you go to File > Export within the PDF tab what is the area set to? If possible could you provide a screen recording that demonstrates this issue or a copy of the file? If you create a test file with a few pages and try exporting it do all pages export?

Thanks
