Labelling Options – bug

Hi! Sorry but I’ve detected other problem in: Options – Labelling Options – Product Page

I’ve written different tags in my language, and when I save changes, it doesn’t change anything:

https://suculaff.com/especies/no-suculentas/product/euphorbia-lamerii/?

“Product Details” = it should appear “Detalles”
“Additional Information” = it should appear “Info Adicional”

In Sidebar and Catalogue Options is working correctly!

Thanks so much.
