Inquiry about locating and correcting the initial value type of the "availability" variable

Hello Shopify Support,

I hope this email finds you well. I have been testing my website’s SEO using Google’s SEO tool and have encountered an issue where the “availability” variable is holding an incorrect value.

To resolve this issue, I need assistance in identifying the section within Shopify’s admin panel where I can locate and correct the initial value type of the “availability” variable. Could you please guide me to the specific location in the admin panel where I can check and modify this variable’s value?
