[2021] Private World Help

Hi all, I just started a private world with my friends and they are new while I have played a little bit. I wanted to give us all exactly one extra star to specialize things but somehow I f*cked up kinda hard. I tried to give myself one star and typed /point (NAME) 1 and it gave me 10,000 points... I did it again in a different way to see if I could get a star only but now I'm level 20 and I can't go back down to level 1. Help is much appreciated!!! I tried /point (NAME) -negative number but it just resets my current skill bar and doesn't devel my character.
