I’m seeing this as well:
Advanced Custom Fields: Options Page
You have version 1.2.0 installed. Update to 1.2.0. View version 1.2.0 details.
It only shows up sometimes. Like I’ll have a list of updates, run them, and then this one will show up afterwards, if I switch between the plugins page and the updates page sometimes it goes away for a bit, but seems to keep coming back. I’ve got it on a handful of different sites and a couple different hosts and seeing the same on all of them.
Happy to help debug if needed.
