It seems the hierarchy uses the level name, instead of caption (https://jsfiddle.net/wkL7et18/12/). Shouldn't it use caption like non-hierarchy types?
Hello,
Thank you for writing. Currently, the level fields do not have own caption
property. If you need to specify caption we recommend setting the correct value for the level
property.
Let us know if everything works fine for you.
