Zeladoth alpha bad spawn

Been hunting zeladoth alpha 3 days at these location
131836 87268
137993 87233
today notice that Zeladoth alpha are spawning very rare ,just zeladoth beta spawn insted ,can you increase spawn zone like 50 -100 more alpha, now i need to fly evry time and search for theam and that annyoing

 

If you continue to kill only Alphas then after a while all you will get is Betas. There is a chance for each mob that spawns to be either Alpha or Beta. So you understand how leaving Betas alone will make the Alpha spawn smaller by time.

 

that so wierd way ,mobs shoud spawn like in evry other planet

 

Actually it is the same on every planet except LAs. Only difference is that on other planets you get hundreds of mobs around so you don't notice that so much (or at all).
