Summary:
We are located in Czech Republic (central Europe).
There are two AirPort Extreme AC basestations in our company.
We are trying to set 5 GHz channels for AC Wi-Fi on both of them so they do not overlap.

According to Apple SP680 document AirPort Exterme AC should support  following channels in Europe https://support.apple.com/kb/SP680
"Channels 1-13, 36-64, and 100-140 approved for use in Europe and Japan".

However there are only 4 settings for 5 GHz channel in AirPort Utility: 36, 40, 44, 48.

Our current setting is 36 on first and 48 on second AirPort. However you can't fit two 80 MHz wide channels so they do not overlap. See attached screenshots.

I believe there shoud be settings for channels in 50-64 range.

Steps to Reproduce:
1. Open Airport Utility
2. Connect to desired AirPort Extreme AC Basestation
3. Go to Wireless -> Wireless Options...
4. Counry is set to Czech Republic
5. Configure 5 GHz Channel:

Expected Results:
Be able to configure channels in range 36-64.

Actual Results:
I am only able to configure channels 36, 38, 44 and 48. That is fine for US but according to Apple specificication SP680 I should be able to set channels all in range 50-64 in Europe.

Version:
AirPort Extreme 802.11 ac A1521

Apple says

You can’t manually set a DFS channel. Thats specified by regulatory bodies. The only way those channels are selected is through auto channel selection
