Guild Wars 2

I created 3rd Ranger, leveled each to lvl30, tamed many pets, but still don’t have completed hint Ranger Pet Panel.
But some player told me, that he completed it on lvl13.
What should I do?
Thanks for help.

Even though you have tamed a lot of pets make sure you have done all of the following.

Ranger Pet Charm

• Approach any juvenile creature and press F to charm them.

Also:
To get the Ranger Pet Swap hint, you are required to let your pet die and not swap it. After a few seconds the hint will appear.

Ranger Pet Controls

• Order your pet to heel, use special abilities, and attack your target by using the pet controls F2.

Ranger Pet Panel

• Open your Pet Management panel to equip different pets, rename them, and view their statistics.

Ranger Pet Swap

• Call in a new pet F4, and your current pet will be healed and ready for action.

Open your Pet Management panel to equip different pets, rename them, and view their statistics – This I did, I opened panel pressing “K” renamed all 3 pets which I have, but still dont have this hint…

Rest of hints appears between 1-10 lvl, but this not.
