Receiving incorrect data from cartLinesAdd and cartLinesRemove mutations

[AndriyLitvinyuk]

If we are using cartLinesRemove mutation, we are receiving the correct empty cart from the response, but if after that in quick succession there will be used cartLinesAdd on the same item, the endpoint returns the old cart item + new quantity Had 1 item with a quantity of 3. Response from remove mutation:

 Result <Mutation: ["cartLinesRemove": {
    cart =     {
        lines =         {
            nodes =             (
            );
        };
    };
}]>

Right after that response from add mutation with the same item with quantity of 3.

Result <Mutation: ["cartLinesAdd": {
    cart =     {
        lines =         {
            nodes =             (
                                {
                    "__typename" = CartLine;
                    id = "****";
                    merchandise =                     {
                        "__typename" = ProductVariant;
                        id = "****";
                    };
                    quantity = 6;
                }
            );
        };
    };
}]>

I tried disabling the cache for the client and URLSession, and it's not helping at all. CartId is the same, updatedAt in the responses is correct as well.
