Wall Finish - Wall being created in just one room

Hi! I’m quite new to the dynamo world so this may be a stupid question …
Why are the walls from my script beeing created in just one room? Am i missing something?

Since i’m a new member i can’t upload any files, so here is the link to a google drive folder
