Duplicated planes at Ibiza (Simwings)

I bought the Ibiza payware airport from Simwings / Aerosoft (tried to post this in their forum, but for some reason it doesn´t work).

I´m having a problem.

For some reason, I get duplicated IA aircraft in the same spot.

Here are some screenshots.

Superimposed A330 and A320:

Two A320s in the same spot, mixing the textures (you can see by the winglets, that there are actually two separated aircraft):

Yes, I have changed the AI default textures (really ugly) for those from Iberia / Vueling / Spanair, but that is not relevant, the problem persists with the default textures (in fact, I wish I could do it with those ugly A330s too).

I see nothing about this in the Aerosoft forum, so I guess it is not a generic problem with this scenery.

It´s like my system is drawing both the payware and default scenery at the same spot.

Anybody knows what can be happening here?

Thanks very much.

Sorted this out by disabling ground traffic aircraft. But then obviously you won’t see any at other airports.
