Using AWS basic Station, found TX power to be 0.0dBm EIRP

After my test, the power of TX will be 12dBm, the lowest power of SX1301, Generally, transmission power is a parameter that is controlled by the LNS. I guess there is a server configuration problem or there is a problem with my configuration file, Am I missing something important?

2022-06-22 01:57:17.532 [S2E:INFO] TX ::0 diid=39028 [ant#0] - on air: 925.7MHz 0.0dBm ant#0(0) DR10 SF10/BW500 frame=20309C905190DF9AD2E59C5E..DE87E47C

Or is there any other relevant information I can continue to provide,
