Hey there Mullâh,
I was able to find an old forum post for exactly the same issue and it appears to be intermittent bug with Venthyr. Relog your Warrior will fix it.
Can I get you to also submit a bug report ingame if you get a chance? This helps with the player impact tracking they see as not everyone reaches out to us.
I also moved this over to the UI and Macro forum for better coverage.
