Warning pop-up when moving leads to lists

In my campaign I filtered the leads by 'Bounced'.

I then clicked 'Select all' -- in my opinion 'Select all' means select all in this current filter -- and moved what I thought were the bounced leads to a separate list.

Except every lead from the campaign was removed and added to this separate list.

There should 100% be a pop-up warning e.g. "Are you sure you want to remove all your leads from this campaign?"

Very frustrating.
