Bug Issue – Fret Trainer - Learn Fretboard Review

Hey what’s up with your program? I bought it thinking I can learn the fretboard better, but you guys need to fix some bugs or I want a refund. There’s a bug when playing note names. Let’s say I just want to learn just the 4th fret. It keeps on trying to teach me the B note on the same string. It also won’t register correctly when I choose sharps or flats to play the 4th fret challenge.
