My filler valve is leaking from the top valve. I have replaced both seals contained in the repair kit but it still continues to drip from the top valve area. How can I fix this?

I do not know the unit.
But.
Check tension of connections, You may just need to tighten it a bit more, From what you say, you are refering to a cistern, if float does not close valve, it will continue to fill, adjust position of float on the arm.
Other than that, give more details
