If the former "Add Courses" pop up screen displays, with only one search field, then you will need to clear the cache on your browser. If you are using Chrome, click the three dots to the right of the browser address bar, (alternately, select "Settings")> select "More Tools"> then "Clear Browsing Data". Check "Cached images and files" and "Cookies and other site data", then click "Clear Browsing Data" button. Re-enter your login to load the new "Add Courses" screen with multiple search fields.
Please note: Chrome is the only supported browser for COCI, and the system operates best using this browser.
