When adding multiple students to a list, platform notations will indicate if all, some, or none of the selected students are already part of a current student list.
- If none of the students selected are on a student list, the student list check box will be empty, such as the "Freshman" student list example in the screen shot.
- If some of the students selected are on a student list, the student list check box will have a dash "-" to indicate that some, but not all, of the students are already included on that list. The example in the screen shot is the "Student List 2."
- If all of the students selected are on a student list, the student list check box will have a checkmark, such as the example "Student List 1" in the screen shot.
You can click on any of these checkboxes to clear these indications. This allows you to manage which list or lists you would like your selected students to remain on. Then, select the list as the placement for your selected student list.
All this means that when you are adding a student to another student list, if you are removing or checking the check or dash mark, you are essentially removing these students from that student list they were originally on. Could it be possible that when adding a student to a new list, you have been clearing the indication that they also live on another list?
