Noticeable asymmetry should be assessed by your injector to evaluate adding or dissolving product. Lumps and white spots to your lips can be excess filler and can be dissolved after a consultation with your injector.
The white lumps you are experiencing are leftover filler, they can be dissolved with hyaluronidase by your injector.
What you are experiencing is lumps of filler left behind because the Juvederm Vobella was put in in a bolus technique. You can have the lumps removed with hyaluronidase. The whiteness is the actual color of the filler showing through the skin because it is too shallow.

The Juvederm needs to be dissolved with hyaluronidase. I use cannulas for this. I also use cannulas for the initial injection and get few side effects and less bumps because I'm deeper.
