Start with alphabates when applied sort

Hello community,
I want sort order in alphabetically when i select ascending order.
I do this but doesn't get proper result.
My query like
{
"query": {
"match_all": {}
},
"sort":[
{
"Name":{
"order":"asc"
}
}
]
}

Result like :

Alliston DuraBlend Salsa Sectional
Austin Red Rocker Recliner
Bishop Red High Leg Recliner
Darcy Salsa Sofa Chaise
Vacherie Salsa Reclining Console Loveseat
Tensas Crimson Sofa
Darcy Salsa Two Piece Sectional

but this is not actual result i think
i want like this

Alliston DuraBlend Salsa Sectional
Austin Red Rocker Recliner
Bishop Red High Leg Recliner
Darcy Salsa Sofa Chaise
Darcy Salsa Two Piece Sectional
Tensas Crimson Sofa
Vacherie Salsa Reclining Console Loveseat

Kind regards,

Could you provide a full recreation script as described in About the Elasticsearch category. It will help to better understand what you are doing. Please, try to keep the example as simple as possible.

A full reproduction script will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer.

A wild guess is that you are sorting on a text field instead of keyword field. Which might indicate that you are using an old version.
