How to Make Simple Queue with rules limitation working on Mikrotik 6.33

I have a brand new RB750r2 mikrotik box with Router OS version 6.33. The first thing I did when got this box is testing the bandwidth limit. That's why I bought this mikrotik box, to do bandwidth limitation.

I configure a simple queue at this box, and It's not working :( . This is just a simple queue with limitation rules. and it's not working. I need a 3 days to figure out why the simple queue is not working.  After 3 days finding the issue then i found the problem. This is because FastPath is enable on the firewall.

How to disable the FastPath to make simple queue working: Go to IP -> Firewall go find "fasttrack connection". and make it disable. and done! Simple Queue with limitation rules is finally working as expected.
