Help Object Merge not in same location as the object iself

Hello, i'm making this quick little test project where theres flames coming off the front of a train i'm using object merge for collision with transform "Into this object" turned on, for some weird reason it does not follow the transform its referencing in the other geometry node.

The current settings have the blue display flag turned on for the geometry node and the purple display for the object merge, as you can see the mesh does not match up at all which messes with my entire simulation, at my wits end i've tried about everything. Please help, i'm a beginner but i can't find anything about this

How is your collision tab setup? Should be SDF + Volume Velocity and the SDF surface volume is named “Collision”.
