Thats not the issue i have reported.
Go here and check the header :
https://www.adp-enseignes.com/fiche/nos-realisations-pour-faguo/
in that page i use a specific PRODUCT TEMPLATE from the product builder feature instead of the default PRODUCT TEMPLATE here with no issue
https://www.adp-enseignes.com/fiche/la-bache-avec-oeillets/
Just compare the header on both URL
Thx.
