Explain why on the 1C side the product does not display properties after unloading from the site?

Question

1C-Bitrix

Help me understand the integration of 1C and a site on CMS Bitrix. Site - Bitrix edition Small Business.
1C - UT 1C 11 (11.4.2139) standard without modifications Exchange module - trade management ed. 11.4 11.4.2.132
I'm uploading a product catalog from the site in 1C, the products are uploaded, but without prices and without parameters. For example, on the site, the product of the Nokian Hakkapeliitta 8 tire has such parameters (properties of the infoblock element) such as: Profile width, Profile height, Diameter joxi.ru/Vm654k3sDgxXLr
no properties:
joxi.ru/EA4n4abhwJDKzm
joxi.ru/DmB1Z7RfwVNjnr
What settings need to be made on the 1C side so that after unloading goods from the site, the goods have properties?
Also, how do I display the prices of the item? On the Bitrix side, the product has a price, but I don’t see it on the 1C side.
