1° PRO 2023 LFE

Good morning,
(My English being very approximate, I rely on google translation)
LFE problem with 1°PRO 2023.
- With 1°PRO 2022, when I put the sound in AAC with several channels in the timiline, during playback and when exporting to the audiometer the 6 channels were displayed (the 4th channel from the left was activated ).And the playback of the LFE in the home cinema worked.
- With 1°PRO 2023, the LFE channel no longer exists at the output, it is not activated. In the homecinema, the bass is no longer restored.
My bad?
Thanks for your help.
