That's the way the source address selection works -- it takes the fib
lookup result and finds the best source address match for it.
Try adding 'src a.b.c.d' to the leaked route. e.g.,
ip ro add 172.16.1.0/24 dev red vrf blue src 172.16.2.1
where red and blue are VRFs, 172.16.2.1 is a valid source address in VRF
blue and VRF red has the reverse route installed.
