Besides, have you checked wether your "high levelled" track is in pre or post fader
set up (just in case : Operations->Pre fader metering)?
Zeus's advice is good if you're in post fader set up. If you're in pre, it's too late, it's the recording level that was too high.
Anyway, I do agree with the others, if you don't hear any clipping or saturation, there's nothing wrong. Most of the tracks in my different songs are showing some of that red and it doesn't hurt at all !!!
