Follow Up Flags and Reminders for IMAP accounts

I’m trying to set a reminder on a message but I only have the option to flag it or to clear the flag. There are no options such as Today, Tomorrow, This Week, Next Week, etc… which I’m supposed to get.

This might have something to do with the fact that I’m using a IMAP account.

Is there still a way to mark my messages for follow up or at least get them to show up as a Task in my To-Do Bar?
