Make changes to the product card for the site on 1C-Bitrix

"The product page doesnt show the value of the "Collection Site" property. As I understood there is programmed option of output of information only for lonely value and when the property is made plural, it is no longer excreted.

"If a property has multiple values, it is not displayed in the card. We have to get through the "/."

"If the Series property has several values, it doesnt display in the card. "Array" is displayed. We need to deduce the values of the array.

"If the Category property has several values, they are not displayed in the card. We have to get through the "/."
