It may be possible that the run is short enough that it did not get
captured, as pg_stat_progress_vacuum is a snapshot of the current
point in time.

Hard to say, but I think that you should update your binaries, at
least.  11.4 has been release in June 2019, and the latest release
available is 11.17, meaning that you are missing more than three years
worth of bug fixes.  Based on the roadmap in [1], 11.18 should be out
next week.
