Dropbox no longer auto-syncing across multiple machines

Please ignore this message, we've found the solution

I asked a similar question to this earlier in the year but we've still yet to find a solution and so I'm asking again. We use Dropbox across multiple Mac computers and rely heavily on saved files syncing across all our machines (online-only is no use to us). With the latest version of Dropbox auto syncing no longer happens and every time someone updates and saves a file on one machine we have to manually go in and click the icon next to every file or folder in order for the file to update and be made available offline. Surely there must be someway to change this so that everything syncs automatically?
