Comment Links not working in Briefed vs Twenty Twelve themes

Comment Links not working in Briefed theme vs Twenty Twelve theme

PROBLEM:
(1) We use the “Briefed” theme. The comment links in this theme do NOT work as expected (more detail below).
(2) As a test, we applied the “Twenty Twelve” theme. The comments links work fine in this theme (more detail below).
(3) The HTML code behind the comment links for both themes are practically the same (copied below) but “Briefed” theme comment links do not open the comments template.

QUESTION:
What is the solution to get “Briefed” theme comment links to work?

CONFIGURATION:
(4) Plugins > Installed Plugins:
[x] WooCommerce
[x] WP Survey And Quiz Tool
(5) Settings > Discussion:
