Adding a new album zzz so it goes at the end of the list works just fine. Adding a new album 111 at the front of the list has the effect that the newly added one fails like the others, but what has now become the 7th album works just fine even though previously it was the 6th album and it failed. i.e. the first 6 fail, and the remainder work
I'll add some more "dummy" albums to my small group and see I can reproduce the problem. It'll be tomorrow now as it's late in the day here.
