[Chiuso] disable the arabic language bar for the product in english and vice versa

Background of the issue:
I am trying to disable the Arabic language bar for the product in English and vice versa. Specifically, I want the product page at link nascosto to show only in English and not display the Arabic version at link nascosto.

Symptoms:
The product page is showing both the English and Arabic versions, but I expected it to show only the English version.

Questions:
How can I disable the Arabic language bar for the English product page?
How can I ensure the product page only shows in English and not in Arabic?
