I made a cuboid system: Players are puting noteblock on the ground and it makes 'region' 51x51x356. My problem is that sometimes (or always, i dont mind) my players are destroing the pstones but it dont destroy the field so they cant place or replace a cuboid anymore (limit is 1). Is there any solution of this?
My config:
force-field-blocks:

• title: CUBOID
  block: 25
  radius: 25
  custom-height: 356
  no-conflict: false

  • 1

I tried your config on a fresh installation and it worked fine. I was able to destroy the field and /ps counts showed no fields existing

Try removing all non-essential plugins and see if the problem goes away, it could be a plugin incompatibility.
