repeater item labels not working in second repeater within two nested repeaters

[jimmy]

wihtin a repeater field (composers) i am using a second nested repeater field (works). For the first repeater item labels show up correctly as defined in the "details" Tab ( "#n: {lastname}" ). The second (sub) repeater constantly displays the label of the repeater field itself ("works") as labels of the items ( ignoring my user definition "#n: {work_title}" ). All items of the nested repeater are labeled in the same way ("works")

Is it a bug or have i misunderstood anything?

 

EDIT: meanwhile i found an identical issue reported on

https://github.com/processwire/processwire-issues/issues/173

seems to be a bug, a possible workaround can be found in the link
