Duplicates not found by MacOS Thunderbird plugin

Hello some how duplicates are not being found still. This is running in Mac Thunderbird

These messages are - I am certain - actually nearly-duplicate, not duplicates. If you try removing comparison criteria one by one using the extension's configuration dialog, you will notice that at some point, a lot more duplicates will be found. The likely culprit is an extra emply line which TB tends to add sometimes, and is picked up by the number-of-lines criterion.
