GPO not applying using computer group as filter

I have a GPO that disables screen saver and I am linking it to a specific OU with a lot of workstations in it.  I created a group, ExemptFromScreenSaver and added the computers I wanted exempt from getting the screen saver to this group so, no matter who logged in, these computers would not have screen saver enabled.

Problem is, the GPO will not apply.  It says the GPO not applied due to filter.  Any ideas why this may occur.  No other filters applied and it is linked directly to the OU where the systems reside.
