Catalogue Creatures Quests.Follow

Hi everyone.

I bought some book from the Sage in the Mage Tower in South Qeynos. And I got this new ability called "Catalogue Creature" so I'm like great, and a quest come with it. Also if you buy other books, you get other quests.

Anyway, so here I got a list of monster to catalogue, so I'm like, piece of cake, right? Well it doesn't work... I keep cataloging a monster for like 5 minutes straight, didn't work.

I catalogue than kill it, doesn't work.
I catalogue and let someone else kill it, doesn't work.
I catalogue and leave it alive and run away, doesn't work either.

Anyone know how that thing work properly?

Well it's just nice to know it's not working, will stop trying like a imbecile ^_^
