Game fails to recognise gate purchased after appearance of aircraft

Similar to a previous post, an X size aircraft wants to land, which was gained in an achievement. Again I did not have a gate of this type but this time I decided to pay some real money and buy some golden aircraft which I then converted into cash and bought an X gate. To my annoyance the game doesn’t recognise that the gate exists so again I will suffer a penalty!

I hope you will fix this soon. Here is a screenshot
