S2400 asking me to rename pattern 1 every time I turn the unit on

Hi all, I’m inquiring about a behavior my unit does after I turn it on. It pops up a dialog to rename pattern 1. I don’t think this is normal. I can only make it go away by hitting OK, which then returns me to the main screen.

Is this normal in new updates? If not, what or how can I fix it?

Thanks
