Spoilboard Z issue

I keep getting an error message when trying to level the spoilboard. That I am exceeding the soft limits. It makes no sense because I carve past that point all the time. I have a 1 inch thick spoilboard so it there is no need to lower the router as it literally has almost 1.5 inches of travel easy before it would bottom out. I cannot find my file I created when I first got the machine. Why is it giving me the error message when I am clearly not past the limit?
