Altium 17, Polygon repour doesn't work, why?

[alonper]

Hi,
I am trying to create GND polygons, at the start everything was ok, but now it seems that I am doing something wrong.
I took a video for trying to create a polygon, while after placing the vertices, "repour all" or "repour selected" doesn't affect. 
what am I doing wrong? 
here you can see the video :

*** OK I just found that the video didn't capture my attempts to "repour selected" and "repour all" , but I did, it just the video game bar that doesn't snap it.. ***

Thanks in advance,
Alon

Open the polygon manager and change the pour order so more important pours fill first

Did you actually assign a signal to it?

Also: placing vias in pads is ussually not a good idea...
