Discover is not showing any data when used date field other than @timestamps

Hi,

I am loading offline logs into ELK and I am using my logDate field instead of the @timestamp field while creating the index pattern in Kibana.

My field appears in the list of fields with the @timestamp but when i used that for the time based filtering nothing shows up in Discover but when i use @timestamp i see the data under discover

I don't see anything wrong with my logDate field it appears same as @timestamp and the type appears 'date' for both, see the image below.

I am converting my logdate time field using date filter already in the logstash config.

How can i make it work?

Thanks

looking at your screenshot there's a big delta between @timestamp and logData .. maybe that's why you don't find anything initially? because the logDate is 9 days behind the timestamp?
