# Entity detection in End to End testing fails when multiple entity extractors both extract the same entity

Here is an example of an End to End test that I put in my tests/conversation\_tests.md file.

```
## Foreign language story
* greet: hi
    - action_greet
    - rewind
* ask_book: Are there any books in [french](foreign_language)?
    - utter_ask_book

```

When I run `rasa test`, I get the following result in results/failed\_stores.md:

```
## Foreign language story
* greet: hi
    - action_greet
    - rewind
* ask_book: Are there any books in [french](foreign_language)? <!-- predicted: ask_book: Are there any books in [french](foreign_language)[french](foreign_language) -->
    - utter_ask_book

```

I think what’s happening is that I have two entity extractors (DIETClassifier and CRFEntityExtractor) that are both independently finding the ‘french’ foreign\_language entity, so it gets duplicated when the test is run. I’m worried this double entity extraction could be affecting my model training. Is there a way to change this behavior?

Thanks

Your model training is unaffected since all extractors are independent. It’s a bug in rasa test. Could you please create an issue on GitHub?

Sure, I’ll submit one now.

I experience the same. When can we see a fix for that?
