how many scans did you do?
maybe it has worked if you only did 6 scans and it has imported 36 las files.
it normally makes 6 las files per scan location.
you can also test the align by selecting it all the cameras and clicking on inspect tool. it will show you the connections between all the cameras. and you look for lots of connections esp. between drone, laserscan and ground photos.
you can also do this while its processing.
