Wall Junction Orders

[Too Long]

Hi team.

I have received a plan from a designer and I just cant get the walls to merge/join without a joint line even though the surfaces are all identical.

I have attached a screen shot of the Junction Orders. if I change the junction orders too much the cavity wall displays incorrectly and/or the joints move.

How can i fix this?

Thanks

UPDATE.

Im able to fix one side by using a column for the brick pier rather than individual walls.
And if I change the wall priority as pictured the joints disappear in elevation but the cavity wall is incorrectly displayed. See pics.

Thanks
