Broker JMS - Durable Subscriprion with Lexical Operators

We have a Broker JMS trigger with filter condition and also durable subscriber configured. But when we added lexical operators in the filter condition, trigger subscribes to only one message and then durable subscriber either gets disconnected or the rest of the messages are queued in durable subscriber.

We have set the locale as en_GB and restarted the broker server.

Since this issue is highly critical, please advise us if you have encountered this situation.
