+Feature: Teachers can't change status variables to have empty acronyms or descriptions
+    In order to update status variables
+    As a teacher
+    I need to see an error notice below each acronym / description that I try to set to be empty
+
+    Background:
+        Given the following "courses" exist:
+            | fullname | shortname | summary | category |
