pusblished site page - site page details discrepency

Our pages in SharePoint online have their Date property displayed in dd-mm-yy format, while this is supposed to be in dd/mm/yyyy format (as per our Belgium regional settings). Is there a solution to this?

FYI:

1 - the page details show the desired format. see attached screenshot.

2 - we are using the OOTB page Properties webpart

3 - the date format in ListViews is dd/mm/yyyy (JSON formatting as the only solution)
