Thank you for your post.
What I would suggest doing is either of the following:
1) Manually edit the internal skin so that it connects as you need it to.
2) Align the inner skin (i.e. frame) together in one of the below options (see attached image), then manually edit the outer skin so that it lines on in the correct position.
Please note that any manual edits will be reverted to the default state if the wall is redrawn or edited.
Would you be able to let me know if this works for you?
