Start and end date on the same line. Date Picker Range Python Dash

I'm using Date Picker Range from dash components in python. However, in the documentation it has the start date and end date on the same line, but when I do it it is on two lines. Does anyone know how to adjust this?

in my code

in the documentation

thanks in advance!!!

My code:

from dash import dcc
from datetime import date
import dash
from dash import html
import dash_bootstrap_components as dbc
    
    
app = dash.Dash(__name__, title = 'Testando format', external_stylesheets = [dbc.themes.LITERA])
    
app.layout = dbc.Container([
    dbc.Row([
        dbc.Col([
            html.P('try dash Date Picker Range'),
            dcc.DatePickerRange(
                            end_date=date(2017, 6, 21),
                            display_format='MMMM Y, DD',
                            start_date_placeholder_text='MMMM Y, DD'
                        )
        ], md = 12)
    ])
], fluid = True)
