How to fix my data tree structure in this tower facade defination?

Dear friends:

I have a data tree question when I build my tower facade. And I come to look for help.

1. Attached images Screenshot.jpg shows that I want to divide my east facade and north into panels, and i need to cut three lines on each floor ( which indicate the bottom of curtain wall module, middle of curtain wall module and top of curtain wall module. ) . my problem is that north facade bottom was not divided, while only bottom of east facade is divided.

2. I tried to flatten the bottom cluster (Height of Bottom of Curtain Wall, Middle of Curtain Wall, Top of Curtain Wall), And i get what attached image Screenshot Looks correct.jpg shows, although i could get both of the facade divided correrctly, but the data structure is not what i want.

the ideal result data structure I want is {(1,2);(1,2,3,...)}[1,2,3], which means {(east facade, north facade);(different floors)}[Bottom of curtain wall module, middle of curtain wall module, top of curtain wall module]

Grasshopper defination is attached. 

Thanks
