How to short a net and a shape on layout using VIA

Dear Support,

I have a question on how to short a net and a shape on different layers using the NET_SHORT property.

In my schematic I have the situation below:

PGND is the orange shape on L3 and AGND are the two nets connected to the two VIAS.

Using the NET_SHORT property on the two 2:3 VIA I was able to have them connected to the shape.

However, it still seems to be missing the connectivity between the two VIAS that should be provided by the PGND shape.

Is there any way to prevent this? 

Thanks a llot

Francesco
