slay These 2 modules are using the same style of JA ACM: Features Intro : style-4 so if you edit the layout file and remove that col-lg-6 class, it will affect both modules.
I just duplicated these files:
ROOT/templates/ja_morgan/acm/features-intro/style-4.php
ROOT/templates/ja_morgan/acm/features-intro/style-4.xml
to have a new one: style-42 and assign this style for the 2nd module and change:
<div class="col col-md-12 col-lg-6">
to
<div class="col col-md-12">
it's showing in full width now.
Kindly check.
