Hi @joselyntikaltile,
You can add the style below within Appearance>Customize>Additional CSS or Child theme style.css file in order to remove the anchor icon:
.entry-header:after, .entry-child-pages:after, .content-bottom-widgets:after {
content:none !important;
}
If you want to add another icon you can use code of Font Awesome icons e.g.
.entry-header:after, .entry-child-pages:after, .content-bottom-widgets:after {
content:"\f015" !important;
}
Also you can use custom image icon using code
.entry-header:after, .entry-child-pages:after, .content-bottom-widgets:after {
content:url('wp-content/uploads/2017/12/test.png') !important;
}
