I've tried to sync it again, but it appears that the other data isn't syncing to the group library. It appears that only the folders of newly added data has been synced, however, there are no files within them.
That one's actually a server-side issue. We're still investigating, but I've made some changes that might improve things. (Syncs might take a bit longer to go through, but hopefully they won't error out in the same way.) Can you give it a try?
The sync actually appears to be mostly working fine — lots of data was transferred successfully — but it looks like you opened Duplicate Items while it was syncing? Obviously that shouldn't be a problem, but switching in and out of Duplicate Items is still a little buggy in 5.0, and given the size of your library, I'd recommend just letting the sync finish before doing much else. Once it's done, subsequent syncs should be pretty much instantaneous.
Loading the duplicates view should be a bit more stable in build 217.
Thanks for all the bug reports, and let us know if you run into other problems. Your library size is at the extreme edge of any we've seen (and well beyond what 4.0 sync could've handled), so it's definitely useful for identifying areas that still need to be improved.
