Why is "Removed apps and users" using so much data?

[Android Central Question]

I'm checking my Google Fi usage, and #1 on the list is "removed apps and users." Well, there's only ever been one user on my phone, and I haven't uninstalled any applications in the last month. Where could this be coming from?

Welcome to Android Central! Which phone? Has it had any major system updates in the past month?
