Changing tx-power

RouterOS Beginner Basics

I want to increase tx-power on my ax2.
I did updated it in WebFig for both 2Ghz – 24 & 5 GHz – 22. Applied, rebooted but it remains the same as before

[admin@MikroTik] > /interface/wifiwave2/monitor 0
               state: running
             channel: 2462/ax/eC
    registered-peers: 0
    authorized-peers: 0
            tx-power: 15
  available-channels: 2462/ax/eC

[admin@MikroTik] > /interface/wifiwave2/monitor 1
               state: running
             channel: 5180/ax/Ceee
    registered-peers: 0
    authorized-peers: 0
            tx-power: 18
  available-channels: 5180/ax/Ceee

What I’m doing wrong?
