Plugin appears different on two of my sites

Hi – I have multiple sites with this plugin. One that has it is branded as CookieYes and seems much more modern. The name in the Dashboard menu is also CookieYes.

However, on another site I’ve just installed it on, it’s a much older looking interface and the menu item says “GDPR Cookie Consent”.

Both are the free version of the plugin from the WordPress plugin repo.

How has this happened?
