I'm having a problem with emclient loosing emails.

When emclient downloads emails then moves them using the rules feature the emails are not seen in the folder even though there is a number attached to the folder indicating that there is an email there when I open the folder it is empty.  Has anyone else experienced this.  The app has actually lost some of my emails.  

If you are using IMAP, are these emails visible on the web interface for your account?

Are you using the latest version of eM Client?
