On both Course Requests (New) and Course Requests, when a specific section is added to a student's list of Course Requests, no warning is displayed to alert that the section is full. This situation occurs when a section is added using "Add New Record" or "Add Many New Records" or when an existing course request is modified to a new section.
A workaround is to use the View SMS popup on Course Requests (New) to add a specific section. The View SMS popup will display a warning about full sections. Additionally, the View SMS list displays the Max number of seats in the section (Max), the total number of students in the section (Tot), and the numbers of seats remaining (Left).
Programming has identified the issue, and a more permanent fix will be released as soon as it is available.
