Setting the worldview on the map will cause the names of several countries to disappear

[uubbbb]

To save time, I demonstrated it directly in the Style editor. The same is true when generating a map in the foreground.

Without setting the worldview, Russia, North Korea, and South Korea can be seen on the map.

When I set the worldview to Japan or Turkey, the names of these countries disappeared. I couldn't find the names of these countries when I zoomed in or out on the map. Of course, the same is true when the worldview is set to something else.
