ASA 5505 ACL issue

We're having some problems with our ASA 5505. It's letting traffic through to devices that are not permitted access in the ACL. The Packet Tracer in ASDM shows that it should drop packets, but it's not dropping them in reality. To test, I removed the entry in the ACL permitting my laptop access, and I was then denied as I should have been. Putting the rule back permitted traffic again, as it should. However, I have some other devices that continue to be permitted regardless of how I try to deny them. Please help me figure this out.
 
The issue was with our Barracuda web filter. Any device filtered by it is seen as the Barracuda's IP on the ASA. After I added an exception to the Barracuda for the devices' subnet, the Cisco blocked traffic as usual.
