Reminders App

My 32 GB watch is full because the Reminders App Data is taking up 30GB. I’ve deleted the reminder (there was only 1) and all completed reminders. I’ve deleted the app. I’ve restarted my phone and watch. I’ve re-installed the app and nothing has any affect on the size the data for the app. It’s driving me nuts. I haven’t reset me watch and phone because I’m currently away and can’t back them up.

I’ve noticed this has been a problem in the past, had anyone else had any luck with solutions?

Thanks in advance.
