Can't Edit newly added GOBJ objects for MK7 KMP file

[ghost]

Whenever I add a new game object to any track, I can't edit any of it's values. Like Object ID, X, Y, or Z angles. It just has a default "CoinJmap" Object ID with every of it's properties set at 0. Would this be possible to fix or add? Or am I doing anything wrong? Any help would be appreciated. Thx.
