AI Rotation Problem

I am literally stuck on a university project I am already late for, I am sorry to bother you however you are my last hope!

I am following this tutorial on YouTube, currently stuck at this part :

With my project Im stuck at the part where the AI line trace (green line is being updated based on my main char location however you can see on the video the red line and the actual projectiles not being updated. The problem actually may come from the MasterPickupBP and the RifleChild socket that we created and some properties not being inherited. Since I am using Mixamo characters.

I am attaching 2 videos I made, also can share screenshots if needed.

Thank you in advance for even reading this. I would be forever grateful if this gets fixed.
