Hey,

ok. material priority says the outer walls should be priority and the interior walls (with air gap) shouldn't appear on top of the outer walls.
let's check layers...

I guess bring to front / send to back display order could help, as you don't seem have intersecting, but overlapping elements. This is not how it should be done.
Sometimes the GS Help Center or a simple web search can give you advice on how to use Archicad.
This one belongs to basic layer functionality.

Switching the wall reference line side could help also.

If the reference lines don't meet then AC won't process a connection in the normal way, so the walls will just occupy the same space. Sometimes even when they meet getting things to display properly can be a pain, in these situations you can produce a Complex Profile column to correctly display the connection.

Another option would be to offset the solid wall reference lines so they don't meet in their corner and see if you can adjust them to the required connection point on the cavity wall. Unfortunately you may find they try to auto connect to the cavity wall depending on layer and connection settings.
