Hi @axelschweiss,
I will try to help you figure out what is going on.
It is awesome you got rasa x connected with a github-repository. That is the way to go for developing a bot with rasa x. The fact that you do not see the training data files on disk is correct. Rasa X has a database in which it stores all the data that it pulls from your github repo.
We recently released rasa x 0.24.1, and I do recommend that you upgrade rasa x to that version. Several issues were fixed related to the git integration compared to your version 0.23.3.
When you upgrade, can you summarize what method you use to install rasa x, and keep track of any specific steps you have to take outside of the installation steps described in the docs?
