Back to Class Jeans not loading

Hi,
I have this set:
https://www.daz3d.com/dforce-back-to-class-for-genesis-8-males
And the Jeans File does load the shirt :/
If I open the file with Notepad++, I see this at the start:

{
	"file_version" : "0.6.0.0",
	"asset_info" : {
		"id" : "/People/Genesis%208%20Male/Clothing/Back%20To%20Class/Back%20To%20Class%20Jeans.duf",
		"type" : "wearable",
		"contributor" : {
			"author" : "Daz 3D",
			"email" : "",
			"website" : "http://www.daz3d.com"
		},
		"revision" : "1.0",
		"modified" : "2019-09-16T17:45:11Z"
	},
	"modifier_library" : [
		{
			"id" : "DzMeshSmoothModifier",
			"name" : "DzMeshSmoothModifier",
			"parent" : "/data/Barbara_Brundon/Back%20To%20Class/Back%20To%20Class%20Shirt/Shirt_16384.dsf#Shirt_16384",
			"extra" : [

As you can see, the File seems to load the Shirt, I found via CTRL+F over 150 hits for "shirt", so... it seems to be wrong.
Does someone have the correct Jeans loading file? I could load the outfit and try to save the jeans as single item, but... I am not so good with creating Clothes as loadable item 🙁
