Try turning off the slider and create a grid review template.

Seems it could be related to the Widget type review template. Try switching it over to the Post or Page type. That will give you a Shortcode that you can copy/paste in to a regular text widget.

Sorry, everyone. I'm looking at this today and hope to have a fix soon.

Sure. Can you share the URL where I can see the issue? Sounds like some CSS conflict.

You can use this CSS in the custom CSS for the review template.

.wprevpro_t1_DIV_2:before {
color: #695656;
}

You can find hex values here...

More than likely this is some CSS adding some margins on mobile view. I need to be able to see it to investigate. Can you setup a test page?

Try adding this and see what happens...

.wppro_badge2_IMG_4 {
max-width: 32px !important;
}
