I use Chord Crush and I think that there is a bug in the chord progression that is proposed in the Girls’ Generation’ song 소녀시대 ‘Lion Heart’.
V I V seems really wrong to my ear and I don’t think that it in A major eather.
I think that the chorus is in D major and that the progression is I V vi.
Wait, I thought you were talking about the TheoryTab Database. In that case can you send an email to support@hooktheory.com so they take care of that issue?
