Some times i found generated RTs once there hard to remove, seems even erase from the soloist's track menu is not always working.

It might help by first resetting the track to MIDI only, then reselecting the RT again to solve that issue.
Could maybe be that generating your RT soloist track to work again needs some extra steps.

BIAB is quirky, but it's one of the most rewarding music creating programs around. Sometimes it feels like riding a camel with three humps.
With always some old, or needed new emergency roadworks getting in your way. Keep your eyes on the update numbering, they are always fixing something at PG.

But lucky us: we got AA men like Noel, Matt, Pipeline and Videotrack etc around helping us out when this camel has a flat tire or worse ....
