I get the same problem as you.
The vias you placed have no net name, so can't connect its to a zone which 
have a net name.
A workaround is to place the vias AFTER filling the zone and don't modify the 
board any more.

A such SMA connector:

launcher/dp/1608592?Ntt=160-8592

Did you add a net name to the pins of the connector?

If you want to create a zone as a ground plane, you HAVE to choose a net name 
for the zone.

This isn't a good idea, this is a good way to make many mistakes.
