For Compline in the Divine Office, why do the final Marian antiphons change?

I'm listening and following compline that was livestreamed here but the final Marian antiphon at the end doesn't seem to the prescribed Marian antiphon in my Monastic Diurnal. Can someone explain what they are singing here? According to my Monastic Diurnal, it says *From Feb 2, even if the Feast of Purification has been transferred, through Wed of Holy Week*: the Antiphon is Ave, Regina caelorum. https://kerkdienstgemist.nl/stations/1972/events/recording/174223800001972
