EIRP = Transmit power - Losses + Gains
From your screenshot: 14mW Transmit power, 0 dB loss, 5 dB antenna gain.
1 mW = 0 dBm by definition
2 mW = 3 dBm
4 mW = 6 dBm
8 mW = 9 dBm
16 mW = 12 dBm
And 12 dBm (which is the 16 mW transmit power) - 0 dB (cable loss) + 5 dB (antenna gain) = 17 dBm EIRP.
So the EIRP depends on the antenna gain, which makes it possible in your first screenshot that the same transmit power results into different EIRP values.
