The problem is when I change the stem wall height it automatically changes the absolute floor elevation and vise versa. I thought I had the foundation set however this is an addition to a home with a crawlspace and a 7' basement. The addition will have an 8' basement. For now, I went through and reset the defaults and I was able to get the 4" to go away. I had to go back and reset all my other heights. Very glitchy. Autocad user for 30 years and it's very frustrating.
Thanks for your input.
