I don't understand why 'ARTPOP' on my iPhone always shows in 'Artpop'
I tried to change the title to 'ART' or 'ARTPO' or something, and they're both capital.
But when I type 'ARTPOP', it becomes 'Artpop' everytime
Is there anyone got the same problem as me?
iPhone 5 with iOS 7.0.2 btw.
---------------update------------
I tried to add a space after the last letter 'P' and it works



It's 'ARTPOP' on my iPhone.
It's bug I guess?
