Hey, would be great if somebody experienced could help a beginner here.

I have a track and checked it in the demo of Expose plugin and it says I have Phase issues. But in supervision / Multicorrelation it looks fine. Only line that goes sometimes negative is the very very top one. Correlation in supervision looks good too.

Is this a problem? If it is , or if I have such an issue in the future; what would you do / check. How do I find out where the problem is the best way?
