Unable to import project expense - even after export

Hello,

i experience issue while importing project expense on V 12.3.2.
I use a fresh install (no screen customization).
I create a test expense and export every fields (see attachement).


Then, i try to import the same and i get an error
"Contrôles invalides.
Vous devez renseigner à la fois la date et le montant réels"

Real amount as no sense at this point...

Is it because VAT is set to 0% ? This is a problem because whe only use TTC price and don't manage VAT.

Regards,
