Files uploaded to HiDrive have wrong creation date

Hi when uploading files to my Ionos HiDrive, the files get the creation and last edited date from the moment they were uploaded to the Cloud, instead of their actual creation date.

This does not happen when directly uploading (unencrypted) files via the website of HiDrive.
This does also not happen with Ionos Nextcloud.
Im using WebDAV of course.

Edit: This issue does not happen with the Windows App
