Flows are not updated on device on 3 node cluster

Using this distribution: https://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/integration/distribution-karaf/0.5.0-SNAPSHOT/distribution-karaf-0.5.0-20160706.150806-3364.zip

Steps to reproduce bug:
1. Start cluster
2. Start mininet
3. Put flows on cluster via config ds
4. Mininet device should have correct flows installed
5. Put new flows (same as in step 3 but with changed action)
6. Changed flows are correctly in config, but flow-dump shows still old flows on device
