bro packet session spliting when using multiple interface

Hi,

In our setup we use 2 interfaces for capturing bro traffic, one for inbound and another one for outbound traffic, but we have one issue on this, session split issue. we are seeing wrong conn_state flags, and tried different configurations , can any one help on this issue
we are using bro with pf_ring

configuration we tried node.cfg

conf1:
[worker-1]
type=worker
host=localhost
interface=‘eth10 -i eth11’
lb_method=pf_ring
lb_procs=8

Conf2:

[worker-1]
type=worker
host=localhost
interface=pf_ring::eth10,eth11
lb_method=pf_ring
lb_procs=8
#pin_cpus=24,25,26,27,28,29,30,31
