We need more information to investigate this issue.

Does a mailbox rebuild correct the issue?

Please provide your response or results by updating your bug report.

The headers view reveals that the headers are not loaded properly. But as you see in the photo I attached, the message /list/ contains the headers (sender name and subject), just the Details view/pane on the right does not. Does this help you?
