Most fields are having "No results found", except 4, which is "Unique devices", "Device logins", Config changes" and "Unique indexes".
But when I use "Open in search" for these 4 searches, they actually do provide results.
I looked around the answers but do not see similar or same issues reported, and I don't know where to start the troubleshooting.
It's a version 2.5.4 issue, updating to 2.5.5 fixes this.
