Regenerating same world glitch

I've been trying to find a world i like by exploring the first 2 days with walter and his pet woby. But whenever i decide the world is no good, i regen the map. I usually regen the map 2 times before it's actually a different map. Sometimes i get lucky and its a new map right away. Sometimes i get the same map 3 times in a row.

Idk if this is just me but its been annoying me lately.
