Text not fitting to a curve right (or my not understanding it right)

[Gms9810]

Hello all,
Usually I get along wonderfully with XX5 but I'm having a problem with text not fitting to a curve the way I want it to.
This seems simple but I guess I'm not doing something right. I started with a circle, converted it to an editable shape, broke it at 2 points, tried to fit my text to the 'top' of the arc and it doesn't center. Not only does it not center but it doesn't seem to align with the arc at all and I was careful about extra spaces in my text. I KNOW this is something basic and I should be ashamed of myself for not grasping but I must ask for help. I've attached an example of what I want and what I'm getting. I hope I explained it sufficiently.
