validation and key-word extraction in the same user input

Describe the bug

I have been trying to do validation (other-> validation->validation rules) and key word extraction (in user input) but the entity extraction somehow did not work (the entity is extracted but the property was not set to the value). I tried to track it with the bot framework emulator and found out every time the entity extraction is conducted, the LuisV3 trace happens twice one right after another (I assume the second time the entity extraction is set to an empty string, but not sure about it).

I also have a question about the order of validation and entity extraction that is not directly related to this bug: which is goes first? Will the user input get extracted first and then validated?

Version

• Bot framework composer (v2.1.2)
  
• SDK v4

OS

• macOS
• Windows
• Ubuntu

To Reproduce

Steps to reproduce the behavior:

1. Create a new question
2. In ‘User Input’, set property to user.email, value to =coalesce(@email), add @ prebuilt email in expected reponses
3. I think we can forget about validation for now as it works on my end (it is just a regex email validation)
4. See error

Expected behavior

The property should be set to the extracted entity and get validated.

Here you can see the first time the entity did get extracted:

But the second time the entity is set to an empty string:
