Line SOP disappears in merge with Circle SOP

Hello,

When I try to merge a line SOP with several circle SOPs, the lines don’t show up in the merge SOP. Could someone help me understand what is happening and how to fix it?

Thank you!

Here’s my .toe
Circles_Lines.1.toe (5.17 KB)

In the node, hit the ‘Viewer Active’ cross on the lower right.
Then over the geometry view hit ‘w’ to toggle wireframe mode.
Your lines should appear.

They were being drawn black in shaded mode.

Cheers
Rob
