@fabriziotoniolo , sorry about the trouble.
Thank you for the screenshots. That helps. Please try these things and let me know what happens:
Close and re-open the TRIGGERcmd Agent, then check for the missing commands on the triggercmd.com
Change the name of one of your commands, and see if it reflects that change on the triggercmd.com
If none of that works, you can create a new computer by deleting your computerid.cfg and token.tkn file in your C:\Users\(your user)\.TRIGGERcmdData folder, then close and open the TRIGGERcmd Agent. It will prompt for a token like when you first installed it, then it will create a new computer in your account with the same commands (stored in commands.json). Then you can delete the old computer and set your new computer as your default from your profile page.
FYI, you don't actually have to give your computer a voice name if you only have one computer because your first computer is automatically your default computer, and your default computer doesn't need a voice name to create the Alexa devices. It doesn't hurt to give it a voice name though.
