Strange rests

Any idea how to remove these strange rests? This is a file Sibelius made into a musicxml and then Dorico opened it. I already did some cleaning, but am not able to remove this bar.

Free - Into The Mystic - Van Morrison 3KB+AK.dorico (1.6 MB)

What about using the system track to select and delete mm. 9–11?

Thanks a lot!

Glad it worked. I do that sort of thing all the time in software, not just Dorico.

Cause of those rests was showing in the proofreading panel

Good to know!

Thanks!
