I've got a set of neighborhoods I'm trying to make available as items. They're entered as wkt polygons and they show up fine in the admin interface, but then on the public item page they're all slightly off. This one should be centered over South Lake Ave, for example, and in the admin interface it is. When the items are imported into Neatline, they show up just fine show up correctly where they should be. What's going on, and is there a way to correct this for the public item page? The wkt polygons are in ESPG3857.
