Phase output data when running with Measurements vs time

Hello,

 

I've been using an AD5933 Evaluation board and recently started running some experiments for observing changes in impedance and phase over the time. I used an AD5933 Eval board program (rev B) since it looked improved and can acquire data over the time by setting time and the number of cycles. However, I found that phase data as a function of time show the same values even though impedance data seemed to follow a trend shown in a graph. And I run another experiment making random data and saved it as cvs file. Please see the attched and let me know if there is anthing to solve this issue. Thank you.
