Not sharing room settings between 2 different nodes using hazelcast plugin


I installed 2 openfire servers(nodes) in 2 different machines by sharing same database between 2 different nodes(node1,node2). I enabled clustering(hazelcast). I created a muc room in node1, it is reflecting to the node2 also up to here everything is ok. **when I change the subject or topic of the muc room in node1, it is not reflecting other node2. If I restarted node2 server then it is reflecting back with updated topic or subject. **

But I can’t restart each time to fix this. Please solve my problem
