How can I stop iTerm2 from hiding first line of my clear; ls -F alias command?

I've been using a cls alias over 20 years:

cls="clear; ls -F"

Simply, clears screen, then lists files. It's become a habit now - I cannot stop using it ... However, with the newer releases of iTerm2, (version 3.5.4), this alias is hiding the first line of the directory's files. See Image below. Is there a setting I can use the change this behavior? ![Issuing cls alias results in first line of output being hidden ][1]
