Translation problem with P2 theme

Hi to everyone,

I’m trying to translate this theme in italian, but it seems the words’ list is incomplete… not the all translations are working correctly and I don’t know why, for example the one who says “Hi, %s. Whatcha up to?” in italian is “Ciao, %s. Che cos’hai da dire?” and the result is “Hi, User. Che cos’hai da dire?”… and I cannot find this phrase in the source code
