Slab Recess/Ledge Tool

When I try to use the recess/ledge tool from the +slab menu and close the geometry nothing happens. Smaller geometry works but it won’t function on say a double garage area or larger step downs on duplex slabs. Is anyone else having this issue or know of a work around?

Thank you Josh for sending this across to us, I have sent you an email requesting further information. Could you respond when you get a chance. Thank you
