Thunderbird EMAIL MOVE to folder Fault

Fault Reporting.
Thunderbird MOVE to folder, I selected 2 emails to move to a Local folder, they where deleted from the EMAIL INPUT folder but LOST because in the destination folder there were 2 Email entries created with NO DATA, No Subject and No Body, and 1 of the emails had an Attachment that was also missing.

I have used “move” many times and up until this incident it worked fine. Now I dire not use this feature.
