Smart guitar chord bug with key change??

Question

I think there is a bug in the smart guitar chord selection when changing the song key.
Could someone try this...
Song key set to C major.
Select smart guitar and strum the strings of the Em chord. Now hit the Em chord button to auto strum... sounds the same. So far so good.
Now change song key to C minor.
Do the same for the now Eb chord.. when strumming the strings it still sounds an Em. But notice hitting the chord button plays Eb.
Does anyone else hear this? (it's not only that chord that is wrong)

Answer 1

Thanks guys, I reported it to apple.
It's even more unpredictable though. It seems to me that on a key change the auto strum buttons play the correct chord (not being a musican I am not sure if this is even true, and now I certainly don't trust what it says).
It seems to me that it's the strings that don't get updated properly. Some do, some don't, some do after playing a different chord or playing the chord with the chord button.
Example, between the key of C major and C minor as. before you have a G and a Gm chord.
Play the chord and strum it in C major and it should sound the same.
Change to C minor and without playing any other note or chord, strum Gm... it's still playing G, wrong.
Now strum any other chord and then strum Gm again.,.Now it has suddenly corrected and does play Gm.
As a quick test I changed key to D (major or minor I can't remember) and practically every single strummed chord is wrong.
All I can say is Apples test procedures are woefully inadequate. This is an embarrassment.
