Hi Folks,
My lowest supported rates on 5GHz in global configuration is 36 and I don't have RF profiles configured in groups, but for clients I see 6.0 in supported rates.
WMM Support...................................... Enabled
APSD ACs....................................... BK BE VI VO
Current Rate..................................... m8 ss2
Supported Rates.................................. 6.0,36.0,48.0,54.0
Mobility State................................... Local
Same has been reported in the below post.
If I go to the AP and check #sho controllers dot11Radio 1, there is traffic on 6.0
show per rate stats:

WLC: AIR-CT5520-K9
AP: AIR-AP3802E-F-K9
This is on multiple devices and the device which are showing this has huge difference in speed in what is in dashboard and actual from client machine.
For example: WLC Dashboard is showing 780Mbps, 80MHz, 2SS for 1 client. But a quick netsh wlan show interface on same client machine shows the speed as 173Mbps.
I found one device which did not show 6.0 as supported rates and the speed that client received is 433 Mbps. Interestingly for this client the speed is same in both WLC and in actual machine.
In below debug logs it looks like client is associating with rate 6.0
*apfMsConnTask_5: Jan 17 13:25:09.939: [PA] <redacted MAC> STA - rates (4): 12 200 96 108 0 0 0 0 0 0 0 0 0 0 0 0
*apfMsConnTask_5: Jan 17 13:25:09.939: [PA] <redacted MAC> suppRates statusCode is 0 and gotSuppRatesElement is 1
Unfortunately support has expired and it will take some time to renew it. So TAC is not an option.
