Custom date format in OBI report not reflected when exporting as a CSV

Summary:

Custom date format not reflected when exporting as CSV format.

Content (required):

Hello,

In an OBI report, I'm using a date column (let's say "Candidate Creation Date" for example, but I've tried with many others) for which I put a custom date format :

When exporting the results in Excel format, everything's good and the date format is indeed day/month/year.

But when exporting as a CSV, the date format remains as the default one, with the hours in it :

Is this the expected behavior or am I missing something here ?

Thanks in advance for your help !

Best regards,
