Settings Badge Icon

Hi, I’m using an iPhone 7 Plus, and the badge icon on the Settings can’t be removed. It was a notification from the storage, I’ve cleared up some space and the notification inside Settings is gone, but the badge icon is still there. My iOS is also updated to latest, so it’s not the one that triggers it. I find it annoying because there is no single notification to check.

I’ve tried rebooting my phone, but to no avail.
