Recognizing rasa entities properly

Hi There. I am training two entities as below,

email from [Robert] (from)

assigned from [Mark] (assigned_from)

I have provided ample of examples with multiple combinations. But during testing, when I am providing the input “assigned from Julia”, my rasa is recognizing the input as “from” entity while in actual its assigned_from entity.

How can I solve this issue and can get accurate results? Help will be really appreciated. Thank you.
