They can be fickle things fork seals . I had the same issue with RatatatRat . Forks rechromed , new seals , one still leaked . Took the fork apart again , put the same seal back in … And this time no problems . Did nothing different changed nothing . … Fickle .
Did you do the ‘bit of laminate’ trick? Might just be a bit of crap stuck in the seal?
Naa . I can do a fork seal in minutes on upright forks . It would take me longer to cut the bit of plastic and feck about with it 
Hope it stays good fo:)r you mate
