Extra blank field in "Fields Selector"

[jobeninc]

While attempting to limit the fields displayed in the Fields Selector of a Table by turning off ES dynamic mapping, an additional blank field shows up in the fields selector.

Using default-mapping.json in elastic search config directory:
{
"default":{
"dynamic":false,
"properties":{
"@timestamp":{"type":"date","format":"dateOptionalTime"},
"@Version":{"type":"string"},
"Message":{"type":"string"},
}
}
}

If I remove "dynamic":false, the blank field no longer exists. I am assuming the issue involves attemping to parse the dynamic parameter as an additional field.

This is fixed with the new mapping flattener. Thanks!
