About module Reference

I try to use the Reference module for OMEKA-S and I have a problem when I click on the index I have configured (here, the dcterms:creator field).

Omeka S encountered an error

Entité Omeka\Entity\SitePage avec critère {“site”:1,“slug”:“dcterms-creator”} not found

The URL is as follows :

I configured the Reference module like this :

slug : dcterms:creator

I created a page like this :

Slug URL : reference
Proprieties : Dublin Core Créateur

Does anyone have any ideas?

Thank you in advance
