After our paper is accepted, we got the ISBN and DOI information, I fill those information into tex, but the DOI string runs off the page.
I use the 2017 ACM Master Article Template. Here is the sample code:
\documentclass[sigconf]{acmart}
%\usepackage{booktabs} % For formal tables
%\usepackage{graphicx}
\usepackage{balance} % for \balance command ON LAST PAGE (only there!)
% \usepackage{subfigure}
% \usepackage{url}
% \usepackage{stfloats}
% \usepackage{amsmath}
%% \usepackage{mathptmx}
% \usepackage{color}
% \usepackage{xcolor}
% \usepackage{epsfig}
% \usepackage{endnotes}
% \usepackage{multirow}
% \usepackage{amssymb}
% \usepackage{makecell}
% \usepackage[ruled,vlined]{algorithm2e}
% \usepackage{listings}
\copyrightyear{2018}
\acmYear{2018}
\setcopyright{rightsretained}
\acmConference[SIGXXX'18]{2018 International Conference on XXXX XXXX XXXX XXX}{June 11--15, 2018}{YYYYYY, XX, USA}
\acmBooktitle{SIGXXX'18: 2018 International Conference on XXXX XXXX XXXX XXX, June 11--15, 2018, YYYYYY, XX, USA}
\acmDOI{22.3345/3383733.3390659}
\acmISBN{979-2-4403-4702-3/38/06}
...
...
After I compiles it, the ACM Reference Format will in pdf will looks like this:

What's wrong with my tex to make DOI string running off the page? Is there any way to make DOI string in the next line instead of the same line with other information?
