NCC - SSID settings broken

I have a very simple setup, with 9 NWA210 AP connectet to Nebula Control Center. 

When i go to Access point > Configure > SSID settings, it shows the settings for the first SSID correct. Then when i try, in the dropdown, to select another SSID the client side code breaks, an in the console log, there is a "Must supply a value for form control with name: 'portGroup'" exception.

The result is that only few of the settings is updated on the page, to reflect the chosen SSID, and if you press save, you actually save settings from the first SSID, on the selected SSID. 

In general, the interface seems broken, and often it just ends up unresponsive, and i have to reload the page. 

Behavior is the same in both chrome and edge. 

Are there any way to fix the above?
