In this model the seed points created do not touch the ground, they are above or below the surface of the model, they are usually groups of three points only aligned at several places of the model away from each other.
Next, there are the seed points created with the model visible or not.
I have deleted the job several times and imported from scratch the .3mx model to the editor, I have tried to reduce the analysis of the model from 0.9m to 4.00 m., but the same thing happens.
An other couple of images below again to show the problem.
The version ot the editor is shown below.
