I'm configuring several different layer widgets in my web appbuilder to show only certain layers from the web map. There are two layers in my web map that are not appearing under the 'Choose which layers will be shown on the list' options. Therefore, they are always appearing in the layer list. I don't want to show these, but I can't even see them in the list, and therefore can't untick them. Does anybody know why this may be happening? Is there something unique about these layers that may be causing them to not appear in the list? They are not unique to any of the other layers in my map as far as I can tell.
