The original studio location appears to be different in different scenes. A way to look at it is that they may be recording in different studios. but the original scene where Mario and Willie is introduced to Ronnie the Producer is a different hallway than the scene when LJ tells Mario he is under his contract.
After LJ comes to talk to Mario in the hallway, LJ pushes Mario back into the studio to finish recording. But in the very next scene Mario and Willie is coming out of the studio from a different door than before. The studio door keeps changing.
In scene 3, the bibles are placed differently because there where two different angles. A close up and a wide angle.

Mario Returns from the Video Shoot - Mom asks Mario "What are you going to do?" sense she has her headphones on and it appears she is listening to music, she should have removed the headphones while she was talking to Mario.
Mario tells his Dad he was at a record company meeting - Mario was asked by Bella in a previous scene if he had told his parents about the meeting/contract, Mario had said yes. During the scene with his dad after he signed the contract, his father didn't know about the meeting or the contract. It was never revealed if Mario had lied to Bella about talking to his parents.
When Mario confronts Willie about seeing Bella, Mario walks pass Willie standing in the kitchen. Mario throws the rap that he wrote for his dad on the counter top, but the paper did not land on the counter top, it actually landed between 2 shot glasses. That was real. it was not planned.
The industry party was supposed to be at a club or inside a building. But the scene was shot in the back of a home instead.
