Tannin Bleed advice needed

[Kleankings]

I just completed a deck restore. Stripped the wood (sodium hydroxide), Brightened, and after 72 hrs of no rain, stained with Armstrong Clark semi. The deck looked great prior to staining and even after. I got a call from the customer stating dark streaks/spots are present again. Any suggestions, I would hate to have to strip/brighten/stain again.

I havent seen the deck since we completed 3 days ago. The deck had a pretty even look when we completed.
