After updating to 2016 TexLive (Mac) from 2015 TeXLive (Mac), the BibLaTeX Chicago package (biblatex-chicago), when compiled with LuaLaTeX, repeats the author first name 3 times in the same entry in the bibliography. If I switch back to 2015 TeXLive (Mac), author first names display correctly.
Below is an MWE:
\documentclass[a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[english]{babel}

I believe the problem is related to matters described in these two questions. Impossible to build document with biblatex-chicago
But I have updated. When I try to compile in TeXLive 2016 (Mac), all packages updated, I have to add the following workaround to make it compile:
\makeatletter
\def\cms@choose{cms}
\makeatother
But it issues the following error messages:
Undefined control sequence. \abx@macro@name:given-family ...}{#2#3#1}\if empty
{#2}{}
{\mkbibnamegiven {#2...
I can force it to ignore all error messages, but then the name problem happens, as below.
I delete the AUX files between compile attempts. Also, tlmgr info says biblatex-chicago is on version cat-date: 2016-06-10 17:15:51 +0200, the latest, so I'm not sure what to do.
