How to display no field heading text in the legend for an ArcGIS Online webmap

GISCleanteq

I dont want the field heading to display text in my legend for my webmap.
If I delete the text for the Field Heading under Fields on the right, the Field Name is used in the Legend.
Is there some code that will display a null value heading and not show anything in the legend?

I discovered what I think might be a hack and probably not proper but works great for that. If you go into “Configure Popup” for that layer and even if you have done a custom popup go into “Configure Attributes” and delete the Field Alias in the popup definition. As I said, I am pretty sure this is not how it is intended to work but it works for me and I use it regularly for the education materials I am working on. Let me know if it works for you or if I wasn’t clear in my explanation. Two screenshots included.
