with the new feature "Run Filter" on existing mails I see following behaviour:
First I create a new filter moving incoming mail to a other folder. This works with incoming mails being moved directly to the targeted folder.
If the same filter is being applied to an exististing folder by "Run Filter" the filtered E-Mails are copied and duplicated to the target folder rather than moved.
Is this a bug? The filter Rule says "store this mail in another folder" by moving and not duplicating this E-Mail.
Has someone seen this before and knows how to fix this?
