Empty a bar

Encountered a strange problem, I can’t make bars empty in the middle of the score to redo a passaged. When I select all notes in the passage and press delete or backspace the notes are deleted sure, but all the following stuff moves and fills the now emptied bars. Can’t come up a proper keyword to find help from the help. Thanks.

Check so that you are not in Insert mode.
