That’s generally the default behavior shown on the screen, unless something is causing yours to be different.
Could you paste a screenshot? I expect checkboxes for both, but no yes/no unless that’s how a Mac shows it.
To borrow an image from a different article, this is what I expect. Are you getting “Delete remote files” without the checkbox (making it look mandatory), or not there at all (making it look uncertain as to what will happen)?
