Error when creating agent in Advanced Flow for Agentforce Superbadge

I follow the instruction in step one but when a try to create the agent I get this error: 

Error creating agent : common.metadata.MetadataValueValidationException: Value too long for field: MasterLabel maximum length is:80 More Details: ERRORS : Value too long for field: MasterLabel maximum length is:80 WARNINGS : 

This is the second org I spin with the same result. Worth noting is that when I try to change the language in settings and I choose English I get an error message saying that there is a problem with that country... 

Anyone can help? 

Thanks
