Classic - Cancelaura Macro intermittently fails

So I’m using a /cancelaura macro to cancel reckoning (Prot Paladin talent).

The macro works completely fine, however if I add a buff to myself (like wisdom) the macro then completely stops working.

Is there anything you guys know of that would cause this to happen?
I have log proof of the macro working in a raid setting that I can post if that will help. This is a very weird bug.

What’s the exact macro?

Cancelaura macros are bug ATM.
Here my post talking about it and bringing more info:

They should fix it soon!
