Cannot Change Artist Name In 5.02

[mrmacjr]

Hoster 5.02 Hi I am sure that I am just having brain fade but i was trying to get all the artists to show the same so that when you print song books it does not keep putting up different headers. i.e. Lady GaGa versus Lady Gaga. I was trying to get all of the Lady GaGa songs to show her name with the second capital G but i cannot get the second G to capitalize. I guess the alternative is to change all the GaGa to Gaga but not certain why it will not allow this. thanks in advance
