Hiding Archived items from appearing in O2M lists

I have a O2M relationship between “Projects” and “Tasks”, so that when viewing a Project item, you see a list of Tasks related to it. However I can’t seem to find a way of preventing Archived items showing up in that O2M list.
I thought I could do it by going into the settings for the field and adding a condition with a filter under Interface Options for tasks where the status does not equal “Archived” but that doesn’t seem to work.
Any suggestions?
