Dialogue tree commands not working

Hey! I’m LucWuz and I’m making a Mogeko Castle fangame on Gdevelop. Everything was going well until the dialog tree commands part. The commands simply decide when they will work or not, and most of the time it doesn’t work. the simple command “Train” that makes the variable “FadeOutBlack” become true sometimes doesn’t work, but sometimes it works, which I don’t understand. But, I created another .json (Dialogue2.json) for another dialog (since modifying the first file makes the commands stop working), but in this file NO command works, not even “Train”, which is an already existing command that (again, sometimes ) works in the other file.
