Invalid tar magic when unpacking data of subjects 3-5

[kaufManu]

I've downloaded the individual tar files from the website. I can't untar the files from subjects 3 to 5 completely, but get the following error:

tar -xzvf 20200820-subject-03.tar.gz
...
20200820-subject-03/20200820_144338/839512060362/aligned_depth_to_color_000022.png
tar: invalid tar magic

tar -xzvf 20200903-subject-04.tar.gz
...
20200903-subject-04/20200903_113012/840412060917/aligned_depth_to_color_000047.png
tar: invalid tar magic

tar -xzvf 20200908-subject-05.tar.gz
...
20200908-subject-05/20200908_151833/839512060362/aligned_depth_to_color_000044.png
tar: invalid tar magic

I re-downloaded them several times, but with the same result. Is anyone else experiencing this issue?
