Concern about HP Pavilion Hinge

[TheDriver]

I am using a HP Pavilion 15 laptop that is over a year old. Today, while using it, I noticed a clicking noise around it; while checking my computer, I noticed something odd. As you can see in the picture I posted, for each of the hinges, there is a plastic portion that helps connect both parts of the computer. The one on the left feels just fine, but the one of the right has  a bit of a wobble to it now, particularly if I wobble it up and down. I don't have any issue with opening  or closing the laptop and the hinges themselves don't seem to be loose in any way, but I'm uncertain as to whether this is something to be concerned about.

Update: While further inspecting my laptop, I noticed that the side with the wobbly part seemed to have a small gap that the normal side did not. After taking photos of them for comparison, I also noticed what looked like a chip or some kind of discoloration on the wobbly side (I couldn't see it myself with my own eyes). I've attached the photos here. The top picture is the normal side; the bottom picture is the wobbly side.
