I’m guessing you are using the third-party Dropbox service to sync between your Mac and iPad.
See Problems with Sync from MacBook to iPad
In summary:
- The problem on the iPad, based on the screen shot, is that you have an incomplete sync.
- Try first to re-boot the iPad. This may be all that is needed. After start allow Dropbox time to complete sync.
- The problem could be be incomplete sync up to Dropbox, or incomplete sync down to iPad.
- In the post above, see the link to troubleshooting ideas provided by L&L.
edit. re point 2. reboot mac also in case the Dropbox syncs failed there.
