I think I just found a bug in EarMaster Pro 5 build 578P. When studying lesson 24 of Interval Identification in Standard Tutor, I was given notes F# and G, of which only G comes to my head when thinking Bb major scale.
Here's the screen:

If I am right, the Bb major scales consists of: Bb, C, D, D#, F, G, and A.
Please help me solve my problem,
Michal
