Issue while running multiple nlu projects within same HTTP server


My rasa nlu version is 0.14.2 and the issue is that i have two bots running on same http server with two different endpoints. One bot is in English language other is in french.

My issue is that on passing an utterance to the french language bot , intent is getting picked for that particular utterance which should not be the case bot should report null but it is not . I have checked at my end as if i am inputing any other utterance bot is showing null I am running atleast 3 bots from single http server. Is their any limit to that cz of which bot is misbehaving?

(fyi - both bot projects functions are same just languages are different)
