Membership join date checkbox on constituent detail report has lost its label
On the columns tab there's a checkbox that has no label. It's supposed to be membership join date. I'm not sure when it started but seems to go back to at least 5.20.
In the report the line that defines join_date has always set it to null and that hasn't changed, so maybe what changed is that at some point something elsewhere changed to show blank checkboxes instead of skipping them when the field definition is null.
