Simon -

I would highly recommend upgrading from Quagga 0.99.ANYTHING to the
latest FRR release.  There has been substantial improvements and bug
fixes in the intervening 5 years.

Having said that. Both zebra and bgp are going to have different ideas
of what the routemap is ( hence the show route-map command showing
everyone's view of it. ).
