The bug is in Middlewares/Third_Party/SubGHz_Phy/stm32_radio_driver/radio_driver.h:

SUBGRF_SetRfTxPower expects Tx power level [0..15]. It does checks on power > 15 to select RFO_HP and then it calls SUBGRF_SetTxParams that expects RF output power [-18..13] dBm.

So it interprets power argument incorrectly as it it's index, not dBm while later it's used as dBm. All the client code in https://github.com/stm32duino/STM32LoRaWAN/ uses SUBGRF_SetRfTxPower providing power in dBm.
