Invalid date

Hello,

I am trying to post journal, but it doesn't allow me saying "Invalide date. The datte must be between Jun 01, 2023 and Jun 14, 2023."

This is case excercise for the existing company "Bihn".

The Session date I entered is Jun 14, 2023. and I entered Apr.30,2023 because this transaction date is required in the question.

I tried to change the session date with maintenace and with the date icon, but I can't advance the session date before Jun 1, 2023.

I unchecked  "Do not allow transactions dated before:" in settings.

I even tried "Maintenance--> start new year" without the sucess.

Why it does not allow me to post the journal? Is it because I've already posted other journals ( other dates in June ) and I can not post journal which is prior date to the journal I've posted?

Please advice.

Kind Regards,

K.S.
