AD5686R Output voltages are not as expected

Question

Using EVALAD5686R with ADuCM363 micro controller in SPI mode, with 2.5 reference voltage.
DAC converted voltages are not as expected in few data point. Could you please suggest what might be going wrong?
Below are the data

Hi, 
 Sorry, I didn't see the /SYNC signal on your scope shot. What I'm seeing now is that there are more than 24 clocks on the bus, and apologies as I don't have an eval board on hand, but I'm not sure it would create a valid response from the DAC in this case. 
 Could you try to get the /SYNC waveform and send only 24bits word to the DAC? SPI Mode 1 or 2 should work, with the data valid at the CLK falling edge.

Yes. Issue got resolved. 
 Problem was with sync signal was going high for every byte, that was causing problem.
