Hello - I have a point layer with contingent values that Field Maps Designer in ArcGIS Enterprise 11.5 thinks has true curves. When I look at the layer in the 'Offline' settings in Designer, it shows that this layer has true curves:

I've never seen this before ever,
How is that possible for a point layer? Needless to say, the layer cannot be edited in Field Maps.
It edits in Map Viewer and it edits in a Sidebar with the Edit widget
