'Standardized payouts on a 7 day timer' ?

So the last hardfork reduced payout periods to one single payout after 7 days.

Did it really ? Because I had a payout for a 30 day old post yesterday:

It also shows me a 'Potential Payout' for my posts older than 7 days:

In this case, the payout is 0.00$.

Is it possible, that the single payout period didn't quite go trough and that a second payout is still happening ?

Were two of the four killer features announced here not implemented at all ?

• I can't edit old posts
• I get a second payout window

Is this a bug ?

Did I miss an announcement ?
