Typing names in display weird behaviour

Hi fellow KP users

I have noticed sometimes when typing a new name for whatever in the display, it doesn't automatically step to the next character. I have not been able to understand why it sometimes works and then doesn't. This may or may not be a bug so can anyone tell me why this behaviour is not consistent?

Ahhh it's always a something simple isn't it? It won't step to the next character if there's already one there

Forget I asked.
