how to get rid of red box when commanding npcs

I’m trying to film a scene with an npc walking but it always gets messed up by that red box when you make minor adjustments to their position. Is there any way to get rid of it?

What red box?

Red Box? What do you mean? Make a picture of it.

when typing npc_go into console, if there is any wall near by, like with in 3 feet there will be a red box that appears. I’ll get a screen shot.

Sounds like a script you’ve got installed.
