Undefined actions error in model training

Hello Rasa community!

I am facing a problem when trying to train the model of my project. Specifically I’m getting this error:

I’ve double and triple checked that all of these utterances are properly defined in the domain.yml file like in the image:

This error only occus when trying to train the model in my Ubuntu 20.04 setup in my PC. When the training occurs in Windows OS or in Ubuntu 20.04 in my laptop no problems are detected. Rasa version is 1.10.13.

Any ideas?
