Unsolved Why does the game mess up the jbeam?

The jbeam is not like this in the .jbeam file, nor the 3d model. why does it do this on it's own?
Obviously, i'm talking about the "support beams" from the back of the frame, and to the cab, then back down to the front bumber

 

Coukd you send the node-beam part of the jbeam?

 

Those are collision triangles, not beams

 

hmm why do they appear on their own?
--- Post updated ---

i no longer know where it is as i tried to just make the whole jbeam off the frame (yes stupid, i know) but i can send that one if you want. same problem on that one too

 

No, they're set up in your jbeam files
