Nexus Router BGP - Parser does not parse 'show run bgp' correctly when using VRFs

See original GitHub issue

here is the error that I am getting when I build the BGP with VRF

    output = device.parse('show run bgp')

feature bgp

router bgp 65000
  vrf bgptesting

    address-family ipv4 unicast

if I remove the vrf I would get the result back as expected as shown below (snippet), and it uses a default VRF. However. I am not sure what {instance:default{}} would be for ? I thought this should represent the VRF ? what’s the difference between instance and vrf ?
