Subtotal price and product count in elementor's header cart-menu won't sync


the problem I'm facing with is that the Subtotal price elementor's header cart-menu won't sync, after adding product to a cart. You can see it on the screenshot below.
But after switching to another subpage, for example on shop, the product count and subtotal price in the header will be 0, for some reason. And after adding a product to a cart, the subtotal and product count will be updated, and then again after swtiching to home page, the product count and subtotal in header will be set to 0.
