Flightradar24 doesn't have either of the SQ birds flying, 1 flight each in March and May (C-GOFV C-GXZD)

Regarding C-GFAF, Flightradar says it's flying BOG-YVR on June 14, but AC is selling that flight as 1-1-1 lie-flat. 4 seats not selected
So Flightradar not that reliable for the few days it predicts flights, or has been refurbed?
There isn't a big gap in its flights last couple months to allow refurb
