Midi Bass not working properly, extra wrong notes, and notes not being recognized

Real time bass tracking is difficult and something that has never been “solved” by us or anyone. Unless you go for some special hardware option with seperated
strings or the bass piccolo strings trick with MG3, I think MB1 is the only option, and not so useful except for some creative use perhaps. MB3 is coming but whether that’s going to be enough is uncertain.
