ExpWarehouse - Set Race: Derro

[time_limited]

It is impossible to enable the Derro as a recognizd race within Expanded Warehouse.

Seems like some kind of an error with the dialog box as what You see in the dialog looks like this:
3 Deep Imaskari
4 Derro
5 Goblin
6 Fey

When You click on the Imaskari it is enabled correctly (set to green color).

When you click on the Derro, the Goblin is enabled.
When you click on the Goblin, the Fey is enabled
