Polygons do not completely cover NavigationRegion2D

Question

Hi, I am learning how to use godot from the course and I have come across the following problem with NavigationRegion2D: In the video course when a navigation region is marked, it is indeed covered exactly with polygons as in the picture:

But when I do exactly the same thing, the polygons no longer cover the whole area, but a kind of strange buffer is created:

I have no idea what this could be due to, I compared the inspector from the original project and mine and no setting is different. Do you know what this could be caused by?

This is intended behaviour, please do read the
documentation on navigation regions.
If you want to change it, look for something like the border_size and agent_radius properties

Try changing Agents → Radius in the Navigation Property panel to 0?

At first I did that and it didn’t work but now I moved the node slightly and then the polygons updated lol
