No available pixels on specific building

Also, geolocation seems offsetted by approximately 50 meters towards West when I visualize on Google Earth;

Here you can download the file to test/check;

Regarding the first point, we geocoded the backscatter image to identify the two structures:

It turns out that the lower half of the building is not visible in the backscatter image.

Then we used sarplotter.py to examine the arcs (not unwrapped) in the upper half of the building:

It turns out that there is displacements between scatterers at the same elevation, confirming the Porsche signal from descending track (not shown in this issue).
