Username filter not working in false positive mode

[Famlam]

Compare the following:

• https://osmose.openstreetmap.fr/en/issues/false-positive?item=3032&source=2416&class=30322&username=SekeRob&bbox=
• https://osmose.openstreetmap.fr/en/issues/false-positive?item=3032&source=2416&class=30322&username=Famlam&bbox=

The first link should return almost all reported false positives, the second should return zero.
Instead, both cases, despite setting the filter to a different username, all false positives are returned

Note: it does work properly in 'open issues' mode:
