As the title says, I'm working in Revit 2019. I have a pair of walls that I can't get to join to each other properly. They are the same wall type; they are on the same level with no base offset; wall joining is allowed (they are technically joined, but continue to show a cut line between them); there is no phasing in the project, so that isn't interfering with anything; I've tried pulling each wall back and dragging the control points back together; I've tried changing the wall join style; I've tried pulling the walls back and using trim/extend; I've tried using modify>geometry>join. I'm hoping one of you geniuses can tell me what I'm doing wrong.

Thanks
