Do you have the same issue if you follow the OP’s steps to reproduce it?
yes
Provide extra information to complete the original description of the issue:
There seems to be no way to fly to T42. It shows up in the World Map, and shows up in Navigraph as well. It is impossible to input it into the FMS of the ATR however. I cannot even import it as part of a Simbrief flight plan.
