Error importing project expense

Hello,

i experience strange issue while importing project expense.
I do it several time in the past and it works but today, i can't find the bug...
ProjeQtOr's version is 12.1.2.

I use a csv file with 8 expenses (first problem become with a largest file but i reduce the number of line to track the bug).
 
Note : plannedFullAmount, expensePlannedDate, expenseRealDate and realFullAmount are in english to avoid translation's mystake but nothing change.
I use plannedFullAmount to 1 for expenses that are previously set and avoid error with amount = 0.
CP 2025 and aother are personalized flieds with financial value.
I use idProject because, when using project's name i get an error...

So, this is the log after import :
 

And this is the result :
 

So, fields are well recognized (name of fields are changed to there translation), but i get each time the same error, even with planned date and planned amount not void.

When i try to make it on my 292 expenses to import, i got a time out and log only show "invalid" for each line.

Any idea ?

Best regards,
 

Doing a test with a fresh export structure : copied direct from import screen :
I copy the help line, paste it into excel, set some values according to reference (ie idProject, idStatus, ...) and try to import it, the result is the same :
 

Even if values are presents :
 

Try to create an expense from ProjeQtOr then export to csv, change value (montant prévu) then try to import : same issue.

Even if i use "tout cocher) to be sure to export every values, can't import csv.

Same issue trying in english (perhaps problem with translation ?), so message is in english but no import !
Need to set real date and amount : non sense with status "enregistré" !

And even with these value set, import doesn't work !
