Cleff and enharmonic correction

Hey all,
Trying to use this app to create bass exercises. I've come across two problems so far...
a) the bass Cleff is an 8va too low for standard bass notation. I can't seem to find an icon or option to change this. (was this app written by a guitarist or is it a bug
b) whilst writing in F#, the sharps in the key are correct but places an F natural on the staff instead of E#?
I'm using ipad2 iOS 5
