That's definitely a bug of some kind.  I see the same thing in my
logs:  paypal.com passes DMARC, but paypal.co.uk fails DMARC.  I can
verify that individually, both SPF and DKIM pass for paypal.co.uk, but
when the DMARC library is processing the result, it comes up with a
fail for both, so DMARC fails.

Let's debug a little bit.  Looking in the file I/we use for
"dmarc_tld_file", it contains this for .uk:

// uk : http://en.wikipedia.org/wiki/.uk
*.uk
*.sch.uk
!bl.uk
!british-library.uk
!icnet.uk
!jet.uk
!mod.uk
!nel.uk
!nhs.uk
!nic.uk
!nls.uk
!national-library-scotland.uk
!parliament.uk
!police.uk

I have a hunch that *.uk isn't matching in the library.  Try adding a
single line:
co.uk

I have added it to mine too.  We will see if that changes the
behavior.  If it does, then I will work with the opendmarc developer
to figure out either if it's a bug or if it's something wrong
procedurally with using the opendmarc library.
