Capital letter for slot values

Hi all!

I have a problem with capital letter for my slot values. I have definite slot in this way:
type: categorical
- new york
- london
- moscow

And when I typing “My location is London” - Rasa saves london with lower case to slots. I tried to set values for categorical slot with capital letter but after re-training my model it resets to lower case( Can someone help me with this? Thanks!

Oh, sorry, problem was in my stories data. I used it with lower case :neutral_face:
