Manual Button Routing - not working right?

[Greygirl]

I have menus with chapter buttons on them.

 

There are 3 buttons across in 3 rows.

 

All seems fine with the first 4 buttons, but #5 wants to route to (or as) #7.

 

I try to change it. When I change it to #5, it does NOT change the 5th button to #5, but instead jumps to a button below "saying" THAT one is #5. It will not manually change for me. ... and this goes on for several buttons on that particular menu and the next.

 

Am I doing something wrong? or is there a problem here.

 

Thanks.
