Mavericks: Date Last Opened shows blank in the Hazel log

Greeting Noodlers,
I'm running the latest Mavericks beta with Hazel 3.1.4 and the oddest things happen when I create a rule that keys off of the date last opened field. Basically I created a rule to monitor a folder with "Any File" and "Date Created is not in the last 3 months" and then move any matches to another folder on an external hard drive.
So far so good; however, it appears to move everything, even though if you look at the last opened attribute it has the current date/time. So I went to the Hazel preference pane and looked at the contents of moved folders using the Quick View option and then 'Info' - I see the Date Added, Created and Modified all have current information; HOWEVER, Date Last Opened is blank on SOME folders, but not others (those stay put, BTW).
I've tried other options, such as Date Created, Added, etc. and no matter what I try, it moves EVERYTHING to the backup drive. I must be missing some basic logic here.
Any thoughts? Can I see WHY it matched a file?
Thanks.
