I chose the main floor level of my house to be zero. Garage floor will be 12" above this, as so in the garage room spec window I entered 12" for absolute elevation of the floor. Also entered floor to SWT at 18" and Stem Wall 40". This is shown in my hand sketch 'garage room spec sketch' attached. But when I entered those numbers and hit tab, the abs floor changed to -14 1/8" and the floor to SWT changed to zero. The diagram in the window was also different. That is shown in 'garage room spec'. I hit OK and upon reopening I got different numbers, abs floor -6", floor to SWT 18", and Stem Wall 40" (unchanged). All this is in 'garage room spec2'.
What's going on?
Thanks,
Dan
