Custom skin's camera portrait not stable

[TacticalTilting]

How can I make the portrait camera of a custom model fixed on the model's actual face? When I select a random unit (call it unit X), then I select back the unit with the custom model, the portrait camera is now in a weird "X" place. Then I select unit Y, and I select back the custom model unit, the portrait camera is now in a weird "Y" place. How can I fix this?

Edit: I found out how to fix the problem, you can delete this thread.
