Guitar Rig 7 presets gone

I read that Guitar Rig 7 comes with its own presets. Serarched the forums and found out that they reside in the Common Files section in the program folder. (Please see the included screendump) And, yes, therre they are, but they're not visible in Guitar Rig 7. I klick on the head icon to turn of probably own files (which I haven't created yet. I've tried to work it throug Fil/Import but that doesn't work either. The import presets function does only apply presets made in Guitar Rig 6 (bummer!).
