hi @thinkinnet - this makes sense. I guess it’s because your slot is being filled from_entity with the entity being ‘number’.
One idea would be to use the new entity roles and groups, see NLU Training Data
and forum thread for this. So you would add the role ‘num_people’ to the relevant examples of the ‘number’ entity to your NLU data Then you can add the ‘role’ attribute to the from_entity call.
