Rookie having trouble with disk test

I am running xymon 4.3.17 on both the server and client.  The disk service status graph is not showing a mount I added a couple days ago, but the trends graph is.  I'm pretty green with xymon and can't work out why there's a mismatch between the graphs.  Any help would be appreciated.  Thanks!
