How to move cursor using vim in vscode without forgetting previous column?

Recently I install vscodevim extension on vscode. Everthing works fine except moving the cursor across line bothers me.

Here is current status: (where ---^--- denotes the cursor)

#include <iostream>

int main() {
    std::cout << "Hello world\n";
//------------------^-------------------

    std::cout << "hello world\n";
}

after press jj in normal mode:

#include <iostream>

int main() {
    std::cout << "Hello world\n";

    std::cout << "hello world\n";
^--------------------------------
}

What I want:

#include <iostream>

int main() {
    std::cout << "Hello world\n";
//------------------^-------------------

    std::cout << "hello world\n";
}

after press jj:

#include <iostream>

int main() {
    std::cout << "Hello world\n";

    std::cout << "hello world\n";
//------------------^-------------------
}

How can I achieve this?

Here is my vim settings
