Line tracing doesn't work on objects with no auto collision

Hey all - I set up two line traces with the help from the community but I’m running into an annoying problem

My setup is as follows: when I look at an object that is interactable, a text render appears above it prompting me to press a key which will change the color of the object

Everything works perfectly on an object where I ticked Auto Generate Collision during the import.
However the setup no longer works on an object where I didn’t tick that option and created the collisions manually inside unreal or imported them with UCX in the name from my 3D software

This is very frustrating because there are no visible differences in the settings between an object with auto generated collision and an object where the collisions weren’t auto generated

here are my line traces and object blueprint if ever there’s something in there that needs to be changed

Did I miss anything?
Thanks!
