Guardian drood not showing as a tank

Since i started using logs, our guardian drood is not shown as a tank. We can see him in the report, but not as a tank.
Here s the last log :

Do you know if it s a known bug or i’m missing something ?

Make sure to be logging with Advanced Combat Logging enabled. Network pane of System preferences.

I’ll let you know when im back home. I cant remember if i had enabled advanced combat log. I forgot to tell you that im using the french version of the game , guardian drood is using english version of the game

If somebody is wondering: it works.

I was having the same issue, found this post and although there was no final confirmation I tried what Kihra says and our tanks now show properly.
