Blink previous result before render new result - reactjs

Question

I am new in react and redux. I am fetching data from one page page and I would like to show details of the record. When I click from the list to see details for the first time, it is fine. But when I would like to see the next result details and for a millisecond there is a blink of previous result and then re rendered by the new one. Could you help me with this issue, please? I do not want to see the previous artist detail.
Show details
import React from 'react';
import { connect } from 'react-redux';
import { fetchArtistDetails } from '../../actions';
class ResultDetails extends React.Component{
componentDidMount(){
this.props.fetchArtistDetails(this.props.match.params.id);
}
renderList(){
return this.props.artist.map(artist => {
return(
<div className="ui segment">
<br/>
<div className="ui two column centered grid">
<div className="ui centered massive label">{artist.name}</div>
</div>
<br/>
<br/>
{ (artist.images) ?
artist.images.map(image =>{
return image.type ==='primary' ? <img className="ui centered medium image" src={image.uri}/> : null
}) : null
}
<div className="ui small images">
{ (artist.images) ?
artist.images.map(image =>{
return image.type ==='secondary' ? <img src={image.uri}/> : null
}) : null
}
</div>
<p>{artist.profile}</p>
</div>
);
});
}
render(){
if (!this.props.artist) {
console.log("ahoj");
return <div>Loading...</div>;
}
return(
<div>
<div>{this.renderList()}</div>
</div>
);
}
}
const mapStateToProps = state => {
return { artist: state.artistDetails }
}
export default connect( mapStateToProps , { fetchArtistDetails }) (ResultDetails);
Actions
import discogs from '../apis/discogs';
import history from '../history';
import { FETCH_POSTS, SEARCH_ARTIST, FETCH_ARTIST_DETAILS, CLEAN_ARTIST_DETAILS } from './types';
export const fetchPosts = text => async dispatch => {
const response = await discogs.get(`/database/search?q=${text}&type=artist`);
dispatch({ type: FETCH_POSTS, payload: response.data.results });
history.push(`/results/${text}`);
};
export const searchArtist = text => dispatch => {
dispatch({
type: SEARCH_ARTIST,
payload: text
});
};
export const fetchArtistDetails = id => async dispatch => {
const response = await discogs.get(`/artists/${id}`);
dispatch({ type: FETCH_ARTIST_DETAILS, payload: response.data });
history.push(`/details/${id}`);
};
Reducer
import {
FETCH_ARTIST_DETAILS,
} from '../actions/types';
export default (state = [], action) => {
switch (action.type) {
case FETCH_ARTIST_DETAILS:
return [action.payload]
default:
return state;
}
};

import React, { Fragment } from 'react';

import Header from './header/Header';
import history from '../history';
const App = () => {

};
export default App;

I found and issue (I do not know, if it is proper solution but it works for me)
New action
export const cleanArtistDetails = () => async dispatch => {
dispatch({ type: CLEAN_ARTIST_DETAILS, payload: null });
};
Update reducer
import {
FETCH_ARTIST_DETAILS, CLEAN_ARTIST_DETAILS,
} from '../actions/types';
export default (state = [], action) => {
switch (action.type) {
case FETCH_ARTIST_DETAILS:
return [action.payload]
case CLEAN_ARTIST_DETAILS:
return null
default:
return state;
}
};
And update component
componentWillUnmount(){
this.props.cleanArtistDetails();
}
