```yml
message:

- mapping:
- title: 'id'
- content: 'value'
+ mapping:
+ title: 'id'
+ content: 'value'
```
As you would see, using the ID as a title doesn't seem nice, that's why when a field is empty it would keep the default values, like this:
```yml
message:
url: https://api.chucknorris.io/jokes/random
- mapping:
- content: 'value'
+ mapping:
+ content: 'value'
title: "Chuck Norris Facts!"
```
```yml
message:
url: https://api.chucknorris.io/jokes/random
- mapping:
- content: 'value'
+ mapping:
+ content: 'value'
title: "Chuck Norris Facts!"
content: "Message could not be loaded"
```
