Missing "upgrade to" in GUI

[blackrat5521]

So my unit already has the "Upgrade to" setup from a previous time editing the map (perhaps with a different editor some years ago), when I try to find a "upgrade to" option in the GUI it is not present now. It is present however on structures, but I need to use it through units.

You can run my map as a Player 1 red with a computer in the brown slot and use the item you start with "Droid" and see what I mean. It has the options to "Upgrade to" a few options that are not visible in the editor.

If you compare them, you will see, that Units Trained is missing to. That's because the left one has "is a building" set to true, whereas the right one is not a building. Set is a building to true, edit this field and set is a building to false. Is a building affects which fields are displayed, though most fields still have effects if they are hidden.
