There seems to be duplication/repetition in view of world.
For instance, half of Australia's east cost is shown on the left, and the whole of Australia is shown in the center, and similarly for other countries.
I just want to see 1 country and just want to see it once, not repeated.

You have zoomed out to the maximum on your map. The following settings zoom to 1 view of the whole world centered to show it well:
