Problem with Intersection

Hi I am having an issue where purlings are not showing through a wall in section. Some of them are but not all of them. The purlins have an intersection priority of 10 the wall is made of insulated metal panel and glass the glass has intersection priority of 4. The glass surface is set to 75 transmittances. The walls are all the same composition. One wall shows everything perfectly however the other walls doesn't show everything correctly. I am not sure what I am missing.

Incorrect. purlins are not fully showing through the wall
