Question on scan results from Aruba AP

[Ben Greear]

Someone was connecting our ath10k station to their AP, and it seems the
station only does '/n', even though AP is supposed to be doing /AC.

The AP is an Aruba IAT-225, and it's scan results are below.

I am guessing the problem is in the 'VHT Operation' section?

Or, does this scan actually look valid (and so problem may be on
the station?)
