Not all status showing up for Task Board configuration

I have created some custom statuses for issues, and one of them is not showing up when configuring the task board.

Upon looking at the data in the issuestatus table, I noticed that 2 statuses have the same "sequence" value, and it is one of those that is not showing up in the list.

My test system has these same status, but the statuses do not have the same sequence value. In test, all the statuses show up correctly.

I will correct the data in my production system, but figured I would report this obscure bug so that it can be fixed in a future release.
