I have problems with the radios on the Toliss Airbus in xplane 12. Two flights with the ZIBO 737, all good. In the Toliss A 319 the radio frequencies in P2ATC do not correspond with those in the cockpit or, I have the same active and standby frequency again. I can manually set the ground frequency as the standby frequency. However, after a few seconds the frequency changes to the same as the active frequency. 

I then changed the standby in the cockpit, which resulted in the active frequency being identical to the standby in the cockpit, but I still have two different frequencies in P2ATC. 
To be on the safe side, I tested again with the ZIBO and everything worked again. The strange thing is that the Toliss on the ECAM displayed 'VHF 3 Voie standby'

after a restart of the PC, everythink works in the moment..whatever.... 🙂
