Adding CC Headstones To Selection Dialog

I have spent the better part of the day trying to figure out how to add cc headstones into the headstone selection dialog when you are switching between urn and headstone but it just will not show up. I cloned what I think is the base game headstone, changed out the model in blender, gave my object tuning a unique name/id, added the dialog tuning to my package (along with a whole bunch of other things I likely don't need) and added those under the items to display in the dialog but still, no tombstone. 😟 Can someone please take a look at my package and explain what I did wrong? I have dozens of custom headstones and cemetery items I have bought/converted over the years that I would love to make functional! Thanks in advance!
