Lip filler bump worse after Hyaluronidase (Photo)

I had juverdem lip fillers 18 months ago and instantly got a lump,over time it went down but didn’t resolve so I’ve had 4 treatments of Hyaluronidase but it won’t dissolve. It’s not the same injector I saw for fillers and she is reputable. One of the lumps has gotten worse after Hyaluronidase. How could this be possible and why won’t they dissolve? She’s tried superficial and deeper under the muscle but no luck.
