SRR60 ORBI Pro router enable bandwidth per SSID

Greetings,

In the ORBI Pro setup, running firmware V2.4.2.106, under the Wireless 2 tab, there is a Bandwidth per SSDI section. There is a checkbox to turn it on and the 3 wireless networks shown on a slide control. When you turn this option on it gives you these defaults: 

• Network 1 is set @ 35%
• Network 2 is set @ 35%
• Guest is 30%

However, I can not find a way to change the default %. The balloons above the slide showing the % does increase in size once it's selected, I can find no way to change the %s. Is it possible? If yes, how?

If you can't change the % does anyone know if enabling this would lock the SSID down to that %, even if the other networks were idle? 

Does the enable bandwidth per SSID only work for downloads? I can't tell if the screen is saying download and there is another screen for uploads or just bandwidth metering on downloads.

Thanks!
