I have been developing an application in web app builder using ArcGIS Online version. I am trying to use the Smart Editor Widget for my VGI application. I have configured three widgets which are legend, layer list and smart edit. They look fine on screen but when I started to edit a new feature of institutions (point feature) using the smart editor widget a new layer has been created and added to the Legend and Layer list called "instituations-Editor Cache". I try to use the old Edit widget and it works perfectly but because I want to set up a mandatory field, I used the Smart editor. I don't know how to get rid of this layer from showing up. Please guide me.
I have attached some photo for the problem.
