Adding {-:ean13} to URL causes 404 error

[dominicm]

I have just installed the latest version and having an odd issue where any item with EAN 13 entered in the product page leads to a 404 error. Any product with no EAN 13 number works fine and removing {-:ean13} from "Route to products" also fixes the issue.

Route to products:

{category:/}{rewrite}{-:id_product_attribute}-{id}{-:ean13}

404 URL: domain.tld/index.php?controller=404#/11-colour-black

 

Any idea what is causing this?
