How to get rid of the + sign in the URL when filtering by product properties in Bitrix?

Question

Good day!
Filtering in the product catalog has ceased to work correctly. For example: if the value of a product characteristic consists of one word (the characteristic is "Product material", and the value is "Aluminum"), then filtering by this value occurs correctly. If the characteristic value consists of two words (the characteristic "Material of the product", the value "Steel galvanized"), then filtering by this value does not occur and signs "+" appear in the URL (/filter/material_izdeliya-is-steel+galvanized/apply/ ).
