waveform flipping

I'm testing FM wideband waveform in direct loopback(from port TxA to RXA) through libiio.

when I plotted the I and Q samples from Rx, I'm seeing some flipping of waveform; with flipping keep on taking place at particular intervals. I also attached the snapshot of it.

In the above image you can see the pattern of waveform before 6.93 got flipped after 6.936.

What will be the reason for this happening?

My input waveforms are constant(no flipping). Do I need to tune some parameters?
