Your solution doesn't work for me, I can't see my cert in the window filtering by file extension. My file is called "fake.crt" and I can't see it, or change the filtering process in the window.
Could you copy and paste your configuration file from /etc/NetworkManager/system-connections/ please? (take care to do not display your password).
