How to open multiple bootstrap modals at once?

Question

Bootstrap

Good evening. I got a problem. When opening one window, another one can be called inside it.
When you call the 2nd window, then after its closing the scrollbar disappears from which the 1st window cannot be scrolled. The class is removed from the body, but the 1st window hangs. How to solve this problem?
