How to deal with journals requesting incomplete / incorrect attribution for images taken from other sources?
I don't know whether you can insist on the exact wording the copyright holders asked for, or whether you should, or whether you or the journal faces legal consequences if you don't.
I suggest you write the editor quoting the specific requirements directly as they came to you in support of your wish to honor those requests. If the editor says no and there are consequences that's the journal's problem, not yours.
