Wall Finish Joining

[PhilvK]

The wall below has the finish on the interior side only. The finishes do not join without a line appearing. This doesn't happen if the finish is on the exterior side. Why is this happening?

Same wall type?

Yep, same wall

Items to check.

1) Wall justification lines. Make sure they are  the same.

2) Are these two walls the same type? If not you may need to change one to match the other.

3) Split face applied?

4) Wall joins allowed or disallowed.

5) Is "wrap" checked in your wall type?

These are some of the ideas I can think of right now without looking at your wall types or wall properties.
