Empty List Auto Duplicating

I'm not sure if this is an app bug or an issue with my account but over the last two weeks, I noticed that something is triggering for all my list to appear duplicated. Thankfully the tasks inside the original list are not duplicated in the duplicated list. This issue started happening when a Tutorial List was added on my account which I thought was strange since I'm not new to Bullet and have gone through the same tutorial list before. The lists have auto duplicated again after I deleted the duplicated lists. Not sure what is triggering this issue but on a daily basis, I use Bullet Chrome web app on Windows and MacOS and the iOS app.
