DG WAlls not Cleaning up Properly

Question

OK - I am trying very had to give into they new way of drawing with DG Walls 
 I realize that my dimensions will be hard to work as now I will no longer dimension from one side of a wall to another and have it read 4', it will now read 3'-10 3/4", which the subs will love dealing with. 
 But the problem is they don't clean up right. I am now taking 6 extra steps for every joint between two walls. 
 This is the wall when I tell to extend

I now have to play with the gypsum board to get them to extend properly and to then be cut out where it would not disappear

Is is designed to do this to every joint I create?

It's difficult to tell for sure without seeing the model first-hand, but it's possible that the walls are not cleaning up correctly. I would recommend checking a few sections in the delivered help to be sure whether this is the case: 
"Compound Wall Cleanup Controls" (using the Function attribute in Wall Assembly builder) 
"Wall Intersection Behavior" 
"Dissimilar walls"

OK, I'm assuming you mean what's shown in the top image, correct? If so, the easiest thing to do is temporarily turn off Graphic Group lock and connect the two wall layers as needed (bottom image).

Alternately, the two wall assemblies have their gypsum layers at the same priority level, so I suppose it's a crapshoot as far as which takes priority. I'm guessing this is why nether one does when the wall is treated as an assembly. 
 
 So what I did was to create a new wall assembly where the connecting wall's gypsum layer has a lower priority level (changed to 8). That allows it to automatically cut back to the larger wall's gypsum which is still at level 7, while stud layer cuts to the connected wall's stud layer. .
