How to restrict slot filling in RASA?

I have two slots, filled by two different entities but these two slots might have same value. so how do i restrict the slot filling.

for eg, I need a chatbot for hotel booking and the details that are asked are hotel name and person name. And if there is a hotel ” Hotel Michael” and if the user inputs “Michael” when the question for filling hotel, the slot for person_name is also auto filled and i don’t want that to happen

I tried collecting info using two form but that too didn’t work (I am not sure if i am doing it right)

Also the slot values are reset to None after all the slots of a form are filled, i want the value to persist, What should i have to do?
