Jonathon: Lesser Celandine is a difficult weed to manage. Is it in a pasture or an area with mainly grass such that you wouldn't damage desirable plants? If so, there is some information that the herbicide triclopyr can be effective without damaging the grass.
If there is nothing you wish to save, there are other options. Glyphosate has been the most consistently effective, but timing is everything. The best results that I have seen involved spraying the lesser celandine leaves either before the flowers appear or when just a few are open. Depending on your location, you are either passed that point or will be shortly. That said, it may be still worth doing. Make sure to keep the glyphosate off plants you care about. And please, read and follow all label instructions.
No matter what level of control you think you got in a first spraying, the job will not be over.
