It has to say caught/defeated if you want it to advance the frame. Sometimes if you don't set it up and you only have one, you're forced to switch from blank to caught to blank etc...you count every other page, each time you view the one with a caught poke. Pretty much it makes you do double the flips for the same amount of advancement.
lol thats exactly my problem.... My Caught Pokemon is between 2 useless Journal Pages.... :/
