Chatbot Bug

See the attached screenshot containing two chatbots . They are identical but the first one works and second one doesn't (it returns the error: "Invalid model provided: default.") I have set this up on a demo site with no active plugins except Elementor. See here: https://csnw.com/demo-elementor-test/ After a lot of testing I figured out that it works when "instant response" is set to "on" (chatbot 1) and it doesn't work when "instant response" is set to "stream" (chatbot 2).
