Path for images is incorrect on child pages

So I have a file called cliendland.yaml and I have a blueprint which shows up custom fields for all child pages of /clients/

The issue I am having is that the URL when I do the following:-

{% for key, img in header.custom.ClientHero %}
	<div id="service-hero" class="page-hero" style="background-image: url({{ key }});">
{% endfor %}

The path for key is showing as:


Whereas the file is actually storing it here:


You will see that the issue is that it is adding /clients/, either the file is storing in the wrong location or there is an issue with my blueprint file.

Any ideas?
