Cisco AP power level 1 in UNII-1 and Level 4 in UNII-3

I was testing two Cisco 3602e access points. In The RF profile I had set min and max power to be 14dBm. Therefore I would expect the RRM will set the same power level in both APs

But when I checked the two APs one has power level 4 and the other has power level 1

Then I checked the output of command "show advanced 802.11a txpower". The output below explains why the two APs show two different power level. Because one is using an UNII-1 channel and the other is using a UNI-3 channel.
