Kibana is not detecting Date type

Hi all,

After creating an index with mapping and bulking same data, I found that Kibana was not detecting the type Date for my field 'date'.

My mapping is
"date": {
"type": "date",
"format": "MM-yyyy||MM/yyyy"

But on kibana when I discover my index I found an ? near date field. Kibana is detecting other fields with same type and formats.
I can't create a vizualisation with with x-Axis as Date Histogram on this field.

Any possible reason for this please?

Thank you all.

I had to refresh field list from management -> index pattern and it is fixed.
Thank you all :slight_smile:
