Some B Errors I Couldn't Fix

[brkayacan]

Good day to everyone. The project I'm working on has some B errors that I can't fix. I can't play too much with dimensions and column orientations. Even though I play, the results don't change much. In many places, they wrote that B errors can be fixed by playing with the equipment. However, no matter how much I played with the equipment, I could not fix these errors. Since I'm new to ideCAD maybe I'm playing with the props the wrong way. Since the file is large, I have uploaded it to the link below, thank you in advance.
