I'm not using the Elsevier Article Class, but rather an older LyX template from https://github.com/wwkong/Typesetting-Templates I solved this problem by removing (commenting out) the following lines in the Document -> LaTeX Preamble, that was created by the template: % For Bibliography %\usepackage{apacite} % Order here is important! %\usepackage{natbib} LyX allows you to specify natbib in Document Settings -> Bibliography, and the apacite package is problematic for reasons I don't understand (except that it's known as accidental complexity). Hope this is helpful.
