I assume you are using the correct RT for your tempo or letting BIAB substitute for you? Yes, the introduction of the Very Simple bass was much welcomed by many of us. If it is still too busy you can try changing your whole song to 'A' markers, generate the bass, and then Freeze it. Once frozen you can change your markers back to what you like.

If that doesn't work, some of the MIDI styles have very simple, but solid, bass lines. My personal favorite for Jazz swing is JAZSIMP - mostly in 2 at 'A', and walking at 'B'. Put that through a good synth and it is hard to beat.

p.s. I don't remember if the new Very Simple and Simple have tempo swapping. I added them to my RTTempoSwaps file but don't know if they are there by default now.
