To fix this for 6.1:

1. Open InterfaceAddOnsPetBattleTeamsmodulesGUIGUI.lua
2. Search and replace (ctrl+f or search/replace with your text editor) every "Blizzard_PetJournal" with "Blizzard_Collections"

There are 5 of them in the file.  Make sure "Blizzard_Collections" is capitalized like that and that the _ is an underscore and not a hyphen.


6.1하고 안되시는분들 GUI.lua찾아서 열어서 "Blizzard_PetJournal" 을 "Blizzard_Collections"으로 바꾸시면 된답니다.

이래도 안뜨시면 인터페이스 설정 애드온에서 펫배틀팀들어가서 아래 Reconstruct team한번 눌러주세요.
