Changes Structure after reloading

Hello Bastien Ho,

fist of all thanks for this nice Plugin.
I have an issue with my Mindmap after updating on my Browser (Pc or Smartpohne). Everytime I update my side, it changes order and sometimes two Icons are one above the other, thus its hard to read.

Is it possible that it stays in one position without rearranging?

Thanks ahead
