That's interesting:

ffprobe & ffmpeg 3.4.4 was the ones I used to do this since these are the
versions we use in our toolchain, they report IPPPPPI and ffmpeg is not
able to encode a broken file to a good one.

ffprobe & ffmpeg head: works as Gyan said, reporting I BBB P BBB P BBB P
[...] and ffmpeg is able to re-encode a "broken" file producing a correct
one.

So my problem is solved, I can re-encode the files using ffmpeg head (or
maybe also 4.1).

Sorry for posting without testing the head version, usually I do it!
