Why the moved messages are disappearing in Hawtio ?

Issue

• In Hawtio console we moved about 80 messages from a queue to another queue and they disappeared. We have done this exact action before without issue.
• The queue we moved the messages to was one we had manually created to store messages and so had no producers or consumers.
• The green bubble popup in the top right corner came up saying the messages had been moved. It's like they were just deleted.
• Is this a known bug in Hawtio or is there anywhere i can look to find these messages?
