I keep getting the clipping notice when I try to run a sweep. I turn the levels down and check levels and it says that it is fine, then with out changing the levels I run the check again and it says levels high. There is an inconsistency some where. Any thoughts?

That's because the
Check Levels routine in the Measurement screen and the
Check Levels routine in the Settings screen use different values to generate the pink noise.
The
Check Levels routine in the the settings screen uses the fact that you have the 'check/set levels with subwoofer' pull-down selected.
REW double checks and verifies that the end sweep frequency that you have set in the Measurement panel matches that
subwoofer setting, by the fact that its'
Check Level uses the
end frequency as the pink noise hi-limit cutoff.
So if you had 20KHz as the end frequency to measure for your sweep, you can see how the pink noise would be different (between the two Check Levels) and as such the low level signal you're experiencing.
Set the End Frequency in the Measurement panel to 200Hz..................
