In the options when I press restore defaults for everything the unit system settings dont appear to change. When I export to an .STL the object is too small in the slicer software. But knowing the very issue, I go and set the unit system to millimeters in Moi which usually fixes the problem. But now it appears my model is only half the size in the slicer upon export. In the slicer I scaled by 200% and I (think) that is correct, but no longer in Moi. Now I am so confused about what scale everything is. What are the default settings in unit options? Perhaps I have something checked that I don't want checked. In either case restore defaults button doesn't seem to truly default things. Do I need to delete the .ini file?
