XPS 15 Display hinge issue

Hi guys,

On the left side of my XPS 15 9570 (charging port side) my left side hinge comes up with the lid (as it should) but then doesn't come back down when I close the lid which means the entire part can be up and outside the body! I had a look inside and the only thing weird I could notice was that one of the screws just rotates in place (image attached).

Any ideas on how I could fix this? Thank you!
