This is usually caused by having 2 of the same Assignment Types in your Gradebook. This is usually caused due to teachers creating assignments with those assignment types before they have set up the Gradebook resulting in the Duplicates. This can also affect the Cum Grade from being calculated correctly as some of the assignments with 0 points or weights have nothing to calculate. If this happens see How do I contact Blackbaud K-12 Support? and provide us with the name of the:
  • Teacher(s)
  • Course(s)
  • Assignment type(s) that are duplicated 
We will have the Development Team remove the duplicate Assignment Type, at which time we will notify you and then you will be able to save your Gradebook setup as needed.
