NetFlow export sends two records per flow with egress missing on one (VyOS 1.4)

I am exporting netflow from a VyOS device (VyOS 1.4-rolling-202208291850) and I want ingress and egress data to be included. Before I enable egress reporting, the flow records only include the ingress interface SNMP ID; after I enable egress reporting, an additional flow record is generated with both the ingress and egress interface IDs but I still have the first flow record, without the egress interface ID. This leads my flow analysis tool to over report the inbound data on interfaces. I have tried netflow versions 5, 9 and 10 with the same issue in each case.

Is there some netflow configuration that would give me just the one flow record for each flow, with both interface IDs?

Flow config as it stands:
