Mesh upload problem

[Claurice]

I have been getting this error occasionally that I don't understand and can find no info on it in google.

It says when I select a model "LOD model has no parent"

What causes this and how can I fix it?

Is it a setting in blender when I export it?

I am using the latest Blender 3.2., but it happens in all the versions that I use.

As long as it says "Ship it!" you should be good.
However, if you look closer to the triangle/vertices numbers displayed in the importer, you will notice that all the lower LoDs have the same numbers as the high LoD. Although you have set lower numbers in the Triangle Limit fields. This usually happens when there are vertices sharing the same space. Like when you have the front and the backface vertices at the same cooordinates in space. If you separate those, keeping a tiny gap inbetween the front and back, the LOD generator will be able to reduce the geometry appropriately.
