Import 2×8 Circular Patch Uniform Circular Array pattern into Winprop

I come across the problem with import 2×8 Circular Patch Uniform Circular Array pattern into Winprop. The antenna array consists of 2 rows with 8 elements in each row.

I use the following method to import the antenna pattern of each element, however, it is not possbile to set the location information. Each time I set the x,y,z value, when I come back and check, the value will become back to 0 again.

Is there any bug for this? Could you please give some advice, how to import each element antenna pattern to form the antenna array.

Thanks.
