Effects 901-918 cannot be deleted

It looks like the base effects can't be deleted or moved. I can change the effects to be something else, I can edit the circle effect to be non-circular just fine, but I can't delete or move it. It feels like the console is betraying me when this happens, there is no feedback or message, the effect is just still there afterwards..

If the intended behavior is "you must have some kind of effect in 901-918", I feel like there needs to be a message or a "you can't delete that effect" or something, instead of the "silently ignores the user" that we have currently.
