I have an index 'ABCD'. It already have some data and visualizations.
Now I uploaded some more data( using Excelastic for excel files) that has one new field ( "App Name"). It is a string.
Now when I create a new visualization. Upon selecting Terms as aggregation, the field is available as expected.
Also, "App Name" field is available available in many recent created documents in Discover tab.
But when I try to do the same for pre existing visualization the same field is not available.
Note:- The field is available in Index page as App Name.keyword with String datatype.
I tried to refresh the index from Management > Index Name> Refresh Button but no effect.
The field name is also marked(tick) under aggregatable there.
Why can't I see it in Pre existing visualization dropdown?
What can i do to fix that as I need this field in one of the sub- Buckets.
