Split thrust when using AB autothrust

Hello all,

I have a problem (again) with the AB software. At some part during the flight the AB FCU only controls one engine. The other engine goes to some fixed thrust setting. When using the keyboard in FSX only the engine going to this fixed thrust setting responds. The other one is controlled by the FCU. I attached a picture of it...

I had this problem before and somebody suggested me to start up with a situation with the default Cessna. This has solved the problem at that time but now for some reason it is back.

I am using the latest builds of the airbus suite and the IFDG A319 from the PM website....

Anyone any idea here?

Regards,

Rob
