Even though you have cut the wall away with an SEO, the wall is still there.
The wall will still automatically cut the slab as it normally would if the SEO was not there.
Changing the layer priority numbers of the wall and slab so they are different will stop them from automatically trimming.
Or using a building material in the slab that is stronger than the wall shouls also work - so the slab will cut the wall and not the wall cut the slab.
