You mentioned you want to have some pickup notes in the first bar. To do that you will need to enter the midi which is typically done in the Melody track. When you save this file the default .sgu will turn into a .mgu file. So you have no yet added the pickup notes. No problem, I can add them. Send the .sgu file
.

The gray chord titles (not grayed end of bar marker section) are likey due to you changing the beats/bar so that there are not enough beats to play the later chord. That should be fixable.

BTW, do you have the full chord chart?
