R7000 Model/Device names error

I'm having an issue trying to change Model and device names thru the web browser. Under attatched devices if I select the edit even without changeing anything it will give the error, Invalid device name.(symbol) The only way that it will allow it is to use a underscore in the space. I can change the name thru the app, iOS, but there's no option to chage the Model name. Is there any other way to correct this info? 

I reset the router to factory but it still gives the same error. Any idea what's going on?
