Quick note about intents.
For standard intent cards you need to have created intents in your library and populate them w/ appropriate utterances. Looking at your screenshots it's impossible to say why your Lead Gen intents aren't connecting without seeing all the utterances in your library for each intent.
A shortcut method would be using the AI transition card and adding natural language "intents" that way you don't need to create a library of intents individually. Robert goes into it a bit in this mini tuto
