StaMPS PSI processing clarification

I have been following the RUS Webinar: StaMPS Persistent Scatterer Processing. I have chosen an area in Austria. While following the workflow on the webinar, I have noticed, when we plot certain variables, such as wrapped phase, unwrapped phase, under figure properties, there are certain values, such as number. In my case, this value is 0 or 1 most of the time. Can anyone explain what this number is?

I have conducted all the steps; however, I did not get any error until the end of the processing steps. However, when I try to visualise the data with Stamp_visualizer, I get the following error

Even after selecting a very large radius, as below, I still get the above error.

Following is my annual velocity.
