Date format in SharePoint eSignature

SharePoint eSignature is now available in 28 European countries.
Unfortunately, my latest test shows that the date field in a signature uses US format after the document is signed. It does not respect the site collection regional settings. 

Does someone know from where SharePoint takes the date format or how site owners can change the format? 

Attached is an example of how it is after the document is signed. It should be at least 8/1/2025 (8 January 2025).
