Hunter pet bug

[Kiadus94]

soooo.....
i have a bug on my character
i was taming some crap here and there when i noticed that only few of the beast have a portrait
the ones that do can be stored(saved in the vault or whatever, basicaly freeing up room for more since u can only have 5 on you)
well, the other ones are just whistles and can't be stored or removed
what should or can i do to fix it?
