AC Stair and Railing 2D visibility - SOLVED

[Elemental_BD]

Has anyone experienced the following issue, and know of a resolution - I've modelled a custom post, and used that in a rail, in some instances half of the post is not visible in 2d, whereas in others it is, using the same process/profile to create the different height posts.

Disregard - I switched to a 'profiled post' and used a complex profile in 'quadrangle' setting to achieve the correct display
