Press F5 to open the "Bar Settings" dialog. At the extreme lower left are two buttons: "Reset Bar" and "Reset All Bars". The second one removes all the style and tempo and meter changes. Many arrangements from the internet have a ridiculous number of such things, so you can make them saner with that feature.

But if you're trying to remove shots and holds and rests, you are stuck doing it one chord at a time, as far as I know.
