Nsis7z::ExtractWithDetails not waiting till finished

In my setup i extract several zipped files using Nsis7z::ExtractWithDetails.
Sometimes the installer goes strait to the finish page also the extraction is still running, instead of showing the details page. I'm not able to reproduce this behaviour all the time.

What could go wrong here? Any idea?

Probably the problem is caused by
LockedList:😁ialog /autonext
if the list is empty
