Are you 100% sure you had the top leg inserted properly?
If any of those are really virgin, they sure look like crap to me. Below is a photo of the KV clip. Notice how the diagonal leg (that actually supports the shelf’s weight) is already bent on yours and straight on the KV.I purty sure. They’ve been there for 7+ years.
They’re the clips it came with, Chineseium.
The two on the left fell out, the one on the right hasn’t been used.
Pro tip, use a sharpie to mark where you want the clips.
