Error while uploading date in MM/DD/YYYY format

Hi Experts,

While uploading the characteristic value data through standard MDG upload functionality we are getting error
for creationdate characteristic. Value should be uploaded in MM/DD/YYYY format but it is throwing attached error
"value 12/04/1999 is not numeric".

We have profile defined as MM/DD/YYYY in ECC for this characeteristic.

We tried it with DD.MM.YYYY, it is working fine, but with format MM/DD/YYYY it is throwing error.

Can you please suggest what could be the issue.

Thanks

Regards
