Two cases :
- day D → day D : once the missing label is corrected, the corresponding page disapears from the list of missing labels for the given language (ok, normal)
- day D → day D+1 on the next day, for example this page has been corrected on 30 mars 2022 à 16:07 but it is presented again in the list of missing labels on the 31 mars 2022 at 11:15 for the same reason (…nok, abnormal).
A dummy action open/save with no correction makes the page disappear from the list (=first case) which makes this manual work uselessly redundant.
So I guess there was an action during the night but system was better a few weeks ago (…).
