React-Bootstrap horizontal form not working

I am trying to create a form using react-bootstrap and cannot figure out how to use the horizontal form layout. Below is my code for signin.js.

import React, {Component} from 'react';
import {reduxForm} from 'redux-form';
import {Form, FormGroup, FormControl, ControlLabel, Col, Button} from 'react-bootstrap';

class Signin extends Component{
    handleFormSubmit({username,password}){
        console.log(username,password);
    }
    render(){
        const {handleSubmit, fields: {username,password}}=this.props;
        return(
            <Form horizontal className="col-sm-6 offset-sm-3" onSubmit={handleSubmit(this.handleFormSubmit.bind(this))}>
                <FormGroup>
                    <Col componentClass={ControlLabel} sm={2}>
                        Username:
                    </Col>
                    <Col sm={10}>
                        <FormControl {...username} type="text" />
                    </Col>
                </FormGroup>
                <FormGroup>
                    <Col componentClass={ControlLabel} sm={2}>
                        Password:
                    </Col>
                    <Col sm={10}>
                        <FormControl {...password} type="password" />
                    </Col>
                </FormGroup>
                <FormGroup>
                    <Col>
                        <Button type="submit">Submit</Button>
                    </Col>
                </FormGroup>
            </Form>
        );
    }
}

export default reduxForm({
    form: 'signin',
    fields: ['username','password']
})(Signin);

      

        
        
        
      

    

This is how it is done in app.js:

import React, {Component} from 'react';
import {Route} from 'react-router-dom';
import Signin from '../auth/signin';

export default class App extends Component{
    render(){
        return(
            <div>
                <Route exact path="/signin" component={Signin} />
            </div>
        );
    }
}

      

        
        
        
      

    

This is shown on the page I want both labels to be embedded in textboxes. I went to the react-bootstrap docs several times. I have a copy and paste of their example code for a horizontal form in my code and it still displays similar to the image above. Any help would be greatly appreciated. Thank!

EDIT:

This issue was caused by linking to v4 bootstrap in my html linking to v3 patched.
