Crease when smiling 6 months after under eye filler (photo)

I had under eye hyaluronic acid filler (HLA collection) to help conceal under eye bags. I first had the filler injected about 6 months ago, and then I had two additional sessions after that to inject a little more to even out both sides. I have recently noticed that when I smile, there is now a large crease on the left side of my face. This was not there before. I have contacted my original injector but am waiting to hear back. I feel very self conscious about this. Any feedback about what could be causing this crease (over-filling, migration, incorrect placement, etc) would be much appreciated. I have also noticed what appears to be the Tyndall effect.
