Shape Loader for Train not filling

[carmine prawn]

Hello, I am currently trying to work on moving shapes from far away to be closer to my base, it is a 2 part shape and I currently have half of the shape fully set up with the train running, but when trying to set the other half of the shape up with the shape loader onto the train the loader keeps blinking the shape and not actually filling the box like it should.

the shapes inputted have to be in the same rotation

Ohhhhhh, I honestly would have never thought about that.

Thank you so much haha
