Railing ends disappear when perpendicular to elevation

[ARix]

Hi all,

I am having a small issue where the ends of railings dont show up on corners when they go from parallel to the view to perpendicular. 

I have attatched a few images showing the issue. When I move the end of the railing to be slightly out of perpendicular (10mm in the photo) the edges show up again but are obviously doubled up as you see where the railing meets the wall as well as the lines on the corner.

This is happening with both circular and square profiled rails.

Any advice on what is causing this or how to fix it would be great!

Thanks,

Albi
