"Invalid date" value in CSV report

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):

v 2.11.0 & v 2.11.1

Describe the issue:

I have a date type values in my index, that when written have bigint format - i.e. 1703079084.
In visualization I can see correct value for this field, accordingly to my “dateFormat” configuration in “Advanced Settings”. When I am generating CSV report, that is based on a search on my index, I receive “Invalid date” values for this field in my report.

Would you know what I can check / reconfigure in order to have the values in my CSV report in the same format that my “dateFormat” configuration has?
