traffic with in-network SI getting dropped when analyzer action is applied

R2.21.2 Build 41 Ubuntu 14.04 Juno

vn1-vn3-policy-1 has associated Networks private-vn3 private-vn1 with rule:
pass protocol any network private-vn1 ports any <> network private-vn3 ports any services in-network-si-1 mirror analyzer-1

vn1-vn2-policy-1 has associated Networks private-vn1 private-vn2 with rule:
pass protocol any network private-vn1 ports any <> network private-vn2 ports any services trans-si-1

private-vn1(10.1.1.0/24) is bound to vn1-vn2-policy-1, vn1-vn3-policy-1
private-vn3(30.1.1.0/24) is bound to vn1-vn3-policy-1

ping traffic from 10.1.1.3 to 30.1.1.3 is failing due to "Invalid Source" drops

If i remove the mirror action from vn1-vn3-policy-1, things are fine.

From control-node introspect, Naveen helped me to identify in ifmap that the policy rule for private-vn1<->private-vn3 traffic has only mirror action and no action for SI
