Hi,
it when the  "Incorrect rule configuration" name is thrown, it would really help, if the name object would include the parent object. 
I currently get this error:
Incorrect rule configuration for object "Site".
This got me really confused because there wasn't any rule on the field. In the end I found another "Site" which is a column in an item list.
Incorrect rule configuration for object "Target sites: Site".
Best regards,
Daniel
