My tag endings aren't ending nicely. BiaB 2026(1224)

I have a 12-bar tag, with an "EbMaj7..." in the tenth bar, which I believe should just cause a sustain from that bar, but I still have chords being played in bars 11 & 12. I've tried a rest-all at the end, I've tried RTFS(MOST), I've tried muting, I've tried a few other things. It won't stop nicely.

I don't want an ending after it and if I make the last four bars an automatic ending, it still leaves chords playing and a crash stop.

This isn't critical for me as the song's just for practice, but after a while it starts to irritate and I would like to be able to make nice endings.

I've been through the video tutorial from 2019 and that seems to do what I expect, so I don't understand why it's not presently working for me.
