I have simple data like that:

```auto
{
                "text": "40% 6 tháng",
                "intent": "ask_instalment+information",
                "entities": [
                    {
                        "start": 0,
                        "end": 3,
                        "value": "40%",
                        "entity": "instalment_percent"
                    }
                ]
            },

```

But when i run rasa train, the `%` character has been escape automatically. The warning here

```auto
"regex_features" : [
            {
                "name": "instalment_percent",
                "pattern": "[0-9]{1,2}%"
            }
        ],

```

but still not recognize in Rasa query

Are you sure it’s escaped? How much examples did you add for this entity?
