Restore Lanes in a Comp track?!

I’m liking the new comping but there’s something amiss with it. When I start slicing, then want to adjust or re-adjust my cuts (or create an overlap where a bigger cross-fade is needed), the chopped pieces in the lanes no longer have their audio tales! I’ve tried gluing them, pushing/pushing, everything. The audio is just no longer there and then it starts to get really messy when I fiddle with the cuts, stuff disapearing, moving to new lanes, etc. So is there a way to restore a section and start over while comping?
