Hi,
When I try to configure a new rule (for example visible based in new rule), in the modal, all dropdowns appears in the select with "Dropdown Field" label instead of real label. I attach an image.
I have tested in AEM 6.5 and it works correctly. I didn't see this issue as Know Issues. Please can you check it?
AEM 6.5.12

AEM 6.5

Regards!
