LO Leakage

Question

i have configured the AD9373 to 2GHz Frequency. 
 programed the TX/RX/Sniffer LOs. and configured as internal LO. 
 once the Device programed the LO leakage at the port is -36dBm. 
 i have gone to the Transmitter page on GUI and found when i change the attenuation to 10dB. 
 the Output noise goes dow n , but the LO power increased by 10dB. 
 
 do we need to calibrate the path every time we sett the attenuator?? i dint expected that the TX attenuator will change the LO leakage in opposite direction. 
 
 Please clarify............
