Phase difference between TX channels

I was testing to see if the  phase difference between TX1 and TX2 changes over temperature, calibration , turning on and off and etc'. 

In the measurement i saw that i don't always get the same phase after every on and off but i got these 3 states that were repetitive. Could this be a bug with the AD9371? perhaps it has something to do with TX_Attenuation_delay or a similar mechanism that isn't the same for the 2 channels? Please address this question as this is a critical issue. Both channels output power was the same, with no TX attenuation ( just digital backoff). 


Phase 1





Thank you,
