All

I just created a backing track for Take the A Train.

Here is the first 8 bars and where I'm having an issue

C, C, D7b5, D7b5, D-7, G7, C, C, then repeat that and go to a C9

I created a repeat at the end of bar 8 so it will go back and play those first 8 bars again and then on the second time around, instead of playing two measures of C, it should be one C and one C9 and then on with the rest of the song

What is happening is it does repeat and go back to the start, but it is ONLY playing the C major. It isn't playing the D7b5, D-7, G7 or anything else. JUST the C

Help please
