Question about security protocol used by RT-ACU86U

[StR]

These are the screenshots from the Wi-Fi survey page ( /visindex.asp ) for 2.4 GHz and 5 GHz, respectively.
My router (shown in read in both cases) is RT-AC86U.

I am just curious, what is meant that my router has "AES" (and not AES-CCMP)?
As far as I understand, "AES" is just an encryption standard, while AES-CCMP is a protocol built using that encryption (and it is a part of the WPA2 requirement, as far as I can tell).
So, my question is what type of AES-based encryption protocol is actually used here?

It's just an artifact of how that page displays the information about itself. It can't scan itself so it just shows AES whereas in reality it's the same as the other access points, AES-CCMP.

If you use a Wi-Fi scanner on a different device (e.g. a phone) you will see it show AES-CCMP for the Asus.
