Phase unwrapping anomaly

Hi there
So I’m still beginner in SAR and Interferomtery
I have a problem with phase unwrapping, I follow the exact instruction and step as in this tutorial and the same data

but i get completely different result of unwrapped phase from the tutorial.
And also the snaphu processing product output has naming error for .hdr and .img unwraped phase file see (attachment)
What could possibly I did wrong?

My sistem is
Osgeo 11 distro (lubuntu)
i7 core processor
16gb ram

I tried too using Windows but got the same result
deburst, topo removal, multilooking, filtering

Unwrapped result

it is strange that you have two bands “phase” (=interferogram) in your stack. Do you have an explanation for that? This probably causes the wrong output of the unwrapping.
