TP-Link Archer MR200 - Warning - ignoring EEPROM HT40 power delta

Installing and Using OpenWrt
1

Hi,
can anyone help me please with this error, which is flooding log ? I tried many different configs even disabling HT40 but seems it don't have any effect (at least without reboot yet).
Also is really Maximum transmit power on this router only 8 dBm for 5 GHz or it's indication something is wrong ? The same error occurs also on 19.07.4.
And yes, it's acting as WDS Client and WDS Access point.

Thank you.

Same on ASUS RT-AC51U (21.02).
If HT40 is set, the whole log gets spammed with
