[SOLVED] Absence entry problem

Hello,

We are using version 9.2.4.
This morning, October 15th, one of my project's resources wanted to enter a half day of leave in the past.
She got the following message: "Can't take a start date before" (see attachment).
I managed to enter this request through the absence calendar but not through the absence request screens (I have an external project manager and absence manager profile).

Please explain this situation to me,

Sincerely,

Translated with www.DeepL.com/Translator (free version)   

Here (attachment) is the data entered (before the absence was entered) in the "Earned Absence Entitlement" screen for the resource listed in my first request.
The absences are only followed for the recalculation of the schedule and not for a HR follow-up, that's why the number of days is very high.

Voici (pièce jointe) les données saisies (avant la saisie de l'absence) dans l'écran "Droit d'absence acquis" pour la ressource citée dans ma première demande.
Les absences sont uniquement suivi pour le recalcule du planning et non pour un suivi RH, c'est pourquoi le nombre de jours est très élevé.
