We have a Custom Tab set up for "Pipelines". We have created relationships between the candidate and the pipeline and the req and the pipeline. We have a list view for our pipelines set up that's supposed to sort by Name (a mandatory field) alphabetically.
1) The Name field doesn't sort alphabetically when we first view it.

2) The Name field doesn't sort alphabetically when we click on the field name at the top of the column, either ascending or descending. It DOES sort somehow (the rows change order), but not alphabetically.
