There are not many airports

Hello. I did everything as you advised.
I have UUOL, URRP do not want to be added to the program. After adding and restarting FRrealWX, they are not listed.

Why can this be so? Help

Thank. Adding airports is working. I still did not understand what the problem was. But it works through the "List of airports". Menu -> Tools -> List of airports.
