Steps to reproduce:
1. Setup an all in one or admin node
2. Go to the series tab in the admin ui
3. Click on the arrow to expand the ACL scheduling sub panel for a test series like SERIES 1.
4. Try to click on the + button underneath the ACL scheduling text on the left hand side.
5. Notice that an error of "Error] TypeError: undefined is not an object (evaluating 'str.toString') (jquery.jqote2.js, line 197)"
6. Create a new series
7. Schedule an ACL change for that series
8. Notice that the + button now works for all of the series
