Errors when trying to modify file dates, while OK with Xnview classic

[Enzo]

Hello,
For Xnview Classic soft, I'm using the menu "Modifier la date" (modify the date) for files since years and without any issue.
I'm now moving to Xnview MP and there seems to have sometime unexplained bugs when trying to use the same function.

See the attached screen shots showing an example of the same file with dates fully modified with the old Xnview, while an error appear using Xnview MP. Here attached too, an example of one file in this case.

Thanks in advance for your help to improve your fantastics softs.
