CustomProperties creating duplicate objects and not applying properties

[MichaelvanDiest]

Hello, I'm currently attempting to use the Custom Properties feature of SuperTiled2Unity and running into the following error: Identifier uniqueness violation: 'Name:_MapPrfab/Headquarters/Grid/Objects/Object_7 (TRS), Type:GameObject'. Multiple Objects with the same name/type are generated by this Importer. There is no guarantee that subsequent imports of this asset will properly re-link to these targets.

This error only appears when I place an object in my Tiled map with a custom property. I've followed the steps on the "Custom Properties Support" doc page.

When I open the level prefab in Unity, I can see that the importer has duplicated the objects, one is a Super Object with the Super Custom Properties component. And the other being the prefab replacement. However the custom property is not set on the prefab replacement. Here is a screenshot of it:

I do have the Object Types Xml set in the SuperTiled2Unity settings with the custom properties and everything seems to appear exactly as the "Custom Properties Support" documentation page. Here is a screenshot of my objecttypesxml with the custom properties shown:

Below is the full error:
