ARKit + Core location - points are not fixed on the same places

I'm working on developing iOS AR application using ARKit + Core location. And the points which are displayed on the map using coordinates move from place to place when I go. But I need they are displayed on the same place. Here you can see the example of what I mean:https://drive.google.com/file/d/1DQkTJFc9aChtGrgPJSziZVMgJYXyH9Da/view?usp=sharing

Could you help to handle with this issue? How can I have fixed places for points using coordinates? Any ideas?

Thanks.
