Path for images is incorrect on child pages

Support Forms & Blueprints
1

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:

/clients/user/pages/02.clients/04.main-contractors/contractor-hero-header.jpg

Whereas the file is actually storing it here:

/user/pages/02.clients/04.main-contractors/contractor-hero-header.jpg

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?
