EdgeMAX Egress Netflow

I am using the ER-Lite and trying to collect ingress and egress netflow on my WAN interface. I'm using the following config:

show system flow-accounting

 ingress-capture post-dnat
 interface eth0
 netflow {
     enable-egress {
     }
     server 10.1.10.16 {
         port 4739
     }
     version 10
 }

My collector is receiving the ingress flows, but not the egress flows. I have scoured the forums but can't find any recent information regarding this. I also can't find any wiki articles or documentation from Ubiquiti on how to configure netflow/IPFIX. Can anyone help me out or point me in the right direction?

EDIT:

I am able to see all expected flows on the router by running "show flow-accounting" and "show flow-accounting egress", but the egress flows are not sent to the collector.
