When you first open it and capture the audio..... you will see where the original blobs are. That's the way it displays.
After you run the auto correct (which I advise against) the blobs will be in different positions from that point forward.
A really good idea is to clone that original track for safe keeping.... that way, if, after working on it with ME, you don't like it and have saved it.... you can always go back to the original untouched track.
I advise working manually in your corrections as opposed to allowing ME to do that for you automatically. ME takes it's "best guess" and some of those guesses are wrong. It takes a bit longer to work a track manually but it's well worth the time invested.
You have a valuable tool. I couldn't work without it.
