Soil not giving relative URLs

I am running a dev environment using bedrock-ansible. I then installed the Soil plugin and activated it. I’m getting mixed results with my relative URLs. Some of the stuff the header puts out (location of the CSS file and etc) is using proper relative URLs, but when I try to add in an image, it’s using the whole URL, http and all. This is the code I am using to point to the image:

<img src="<?php echo get_template_directory_uri() ?>/assets/img/crm_logo_white.png" width="93" height="102" alt="CRM Logo">

Am I using the wrong PHP string here to get the URL, or is something not set up right with my setup? I would like to make sure this is properly working before it gets deployed anywhere else.
