Itunes Connect: You must have only 1 Leaderboard as default

Question

I'm getting the above error when I try to create the first leaderboard for my newest app. Does anyone know how to resolve the error?

I do have another app with a leaderboard but surely that won't affect this app. For reference, I'm trying to create a single leaderboard.

This was a bug in iTunes Connect and was confirmed by Apple. The fix has now been released and you should be able to create leaderboards now.
