Trouble getting BFD+BGP working

I have an XG330 running 20.0.2. I'm trying to configure BFD+BGP. The BGP portion works great. However, the BFD portion does not. I enabled BFD from the CLI. The following is what my BGP configuration looks like from the CLI:

Current configuration:
!
frr version 8.4.2
frr defaults traditional
!
hostname bgp
log stdout
!
!
!
router bgp 65002
 bgp router-id 10.3.100.254
 bgp log-neighbor-changes
 no bgp ebgp-requires-policy
 no bgp hard-administrative-reset
 no bgp graceful-restart notification
 neighbor 10.3.100.1 remote-as 65000
 neighbor 10.3.100.1 bfd 3 500 500
 neighbor 10.3.100.1 bfd check-control-plane-failure
 neighbor 10.3.100.1 interface SDWAN
 neighbor 10.3.100.2 remote-as 65000
 neighbor 10.3.100.2 bfd 3 500 500
 neighbor 10.3.100.2 bfd check-control-plane-failure
 neighbor 10.3.100.2 interface SDWAN
 !
 address-family ipv4 unicast
  redistribute connected route-map NOWAN
 exit-address-family
!
exit
!
!
!
!
line vty
 no login
exit
!
end

When I check packet capture on the interface where BGP/BFD is running, I see the following:

It seems like the XG330 is blocking BFD packets destined to itself. I looked under the Device Access section, and there doesn't seem to be any option to get it to stop blocking BFD packets. How do I get BFD working?
