In Preferences there is an option to turn off the automatic fade.
When you pull in clips, the beginning will fade slightly. Apparently it is a feature. To fix it, you'll have to unclick the fade button on the clip. Also, you might have to see it in Arrangement View, look at the drop down box for automations on that audio channel. And then view the fades (or I think you can view it by right clicking the clip and choosing from the context menu). And then you will see the culprit.
Excellent! Thank you
