Rule to Copy to Server is Deleting from Source

I have a very simple Rule to copy emails from my email provider over to my eMClient. Prior to the upgrade to 9.1.2109, when I ran the Rule it worked fine doing the copy. However once 9.1.2109 was installed, the rule now deletes emails from the source (my email provider). When the Rule runs automatically when I start up eMClient, it seems to run fine. Thus the issue only happens when I manually run the Rule.
