The educational license makes no difference in the actual functionality of OmniFocus. There are two possibilities:
1) You have two different versions of OmniFocus on your machines. You can check this easily by choosing "About OmniFocus" from the OmniFocus menu. The two most likely versions are 1.0.3 and 1.5. You'll want to run 1.5 in order to sync between your computers.

2) If the versions are the same, then it sounds like you customized your toolbar. Choose "Customize Toolbar..." from the View menu. Now you can drag whatever buttons you want on or off the toolbar.
