Flow entry in Config DS and not available on device

ODL version:BoronSR2

issue scenario:
Add flow(TunnelOut_1056_2_fa:16:3e:3d:e8:a7) with src MAC, dst MAC and action to physical port 1.
create one moreflow(UcastOut_1056_4_fa:16:3e:3d:e8:a7) with same match condition and action to physical port 2.
config datastore has to flows but OVS has only one flow.
Now delete the flow "TunnelOut_1056_2_fa:16:3e:3d:e8:a7" ,
flow "TunnelOut_1056_2_fa:16:3e:3d:e8:a7" removed in datastore OVS flow also remove.
finally datastore has flow "UcastOut_1056_4_fa:16:3e:3d:e8:a7" corresponding flow is missing in OVS.

step to reproduce the issue:
1.intall openflow plugin features and connect switch to controller.
2.create flow TunnelOut_1056_2_fa:16:3e:3d:e8:a7.

3.check the flow was added in OVS.

sudo ovs-ofctl -O openflow13 dump-flows br-int
OFPST_FLOW reply (OF1.3) (xid=0x2):

4.create flow TunnelOut_1056_2_fa:16:3e:3d:e8:a7.

4.check the flow was added in OVS.

sudo ovs-ofctl -O openflow13 dump-flows br-int
OFPST_FLOW reply (OF1.3) (xid=0x2):
cookie=0x67, duration=18.670s, table=2, n_packets=0, n_bytes=0, idle_timeout=3400, hard_timeout=1200, priority=2,ip,dl_src=00:00:00:11:23:ae,dl_dst=ff:ff:29:01:19:61 actions=output:4

Note :only one flow is present in OVS existing flow over written by new flow action is changed.

5.Delete the flow "TunnelOut_1056_2_fa:16:3e:3d:e8:a7"

URL: http://10.106.138.159:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:73384666687563/table/2/flow/TunnelOut_1056_2_fa:16:3e:3d:e8:a7

6.check the flow was removed in OVS.

[stack@control devstack]$ sudo ovs-ofctl -O openflow13 dump-flows br-int
OFPST_FLOW reply (OF1.3) (xid=0x2):

Note: No flows present in OVS.

7.check the datastore
URL: curl -v --user "admin":"admin" -H "Content-type: application/json" -X GET http://10.106.138.159:8080/restconf/config/opendaylight-inventory:nodes/ | python -m json.tool
