In season one Reba was a substitute teacher at the high school. In season two, she can't find a job because she doesn't have any experience.
The wide shot of the front of Reba's house does not match the close ups. The wide shot has a single door with a wooden screen door to the right of the front. The close up scenes show a double door with no screen doors and a brick return wall to the left. Also a white glider to the right of the door.
In Brock and Barbara Jean's house the framed sunflower picture on the wall behind the house is upside down.
