What is the iOS app alerting me to?

My iOS Nextcloud App always shows me that I have 4 alerts or new messages – 4 of something in “files” but when I open the app, I don’t see anything that would tell me what those 4 alerts are or how I could clear them.

What am I missing here?

Now I have 5 alerts. They aren’t notifications: I only have two of those. What 5 things are waiting for me?!!
