[ovs-discuss] Packets send to tunnel is dropped

I am observing an issue when a packet that reached the switch through a
tunnel is send back to the same tunnel

The packet reaches the swtich for DNAT through a tunnel. The switch sends
the packet to the same tunnel after doing the reverse NAT(using
ovs-netfilter  integration) with a different tunnel id. But the packet
seems to be dropped by the Ovs though it is hitting the openflow rule to
output the packet to tunnel. I am seeing the below entry in dpctl show when
this traffic is live.

packets:3946, bytes:386708, used:0.305s, actions:drop

Is it possible to send packet came from a tunnel back to the same tunnel
but with a different tunnel id or am I missing anything here?
