I'm pretty sure there isn't a bug that's making the sequence return
duplicate values, because if there were, a lot more people would have
complained about it by now.  I think there's probably a bug in your
application logic, but you haven't provided enough detail to figure
out what it is.  I'd suggest examining your log files for clues, and
perhaps posting relevant sections of them here.

It's not surprising that if you're getting duplicate key errors and
you drop the index, you would then get actual duplicate keys...
