Event Outcomes

I have two event outcomes, Win and Loss. I have an Event Result set as primary called Maps Won. For Win, I have condition set to Most Maps Won and it works as expected. For loss, I go to add Lease Maps Won and upon saving it get set back to the drop down item that is just a line “—”. I’ve looked over documentation and such and seems everything is set up correct.

For more reference “Maps Won” has no equation associated with it.
