hi @AdamFerguson . firstly, nice debugging! You’ve run into a limitation there. We haven’t yet made the ‘train’ button in Rasa X compatible with retrieval intents, which I use heavily in carbon bot. My preferred workflow in any case is to train a model elsewhere and upload it to Rasa, rather than training on the production hardware running Rasa X.
We will get round to fixing this, but it’s not top priority at the moment.
