Dual Ball (EXP 139) not allowing baby pokemon

I was playing a quickplay match in the Neo-on (02-03) format and decided to use a Dual Ball. I went into my deck and got a Hitmontop and a Hitmonlee. I had tried to get a Tyrogue, but it wouldn’t let me select it as an option. I bring this up because all baby pokemon cards have a rule in the top corner ‘Baby pokemon count as basic pokemon’. This leads me to believe that this is a bug or just something that was accidental left out.
