Unfortunately the Add-On only works partially for me!

- missing selection: delete all mails, leave one left (per mail)

-a folder with four mails of 3x each exists, but only each mail is found twice
- now delete the found mails
- then a new search
- now comes an error: Javascript application - no duplicates found
- but there are still two of each mail (4 pcs.) available

There are also other combinations of not found mails!
