Stellium auto generate when log in and log out

I have made a server and I'm using stellium but when my members disconnect and they rejoin and the stellium every time it recovers. So I can't make a potion to regenerate stellium to sell to my player:

Here is my server's latest.log: https://drive.google.com/file/d/1bC3u-hL5Qaq3t5q8TAv-ihnatPhh-9-3/view?usp=sharing

I hope dev team will fix this as soon as you can because this is bad for my server
