Fail to import gui-config.json in 3.0.1

[zdyang]

I used shadowsocks-qt5 3.0.1 (appimage version) on Ubuntu 18.04 LTS.
I failed to import my configurations from a gui-config.json file. Once I tried to import a gui-config.json file, a Edit Profile dialog with blank entries pops up. I have read Issue #562 but did not fix it.
A sample json file is attached.
Thanks for your work and any help will be appreciated.

{
    "configs": [
        {
            "method": "chacha20-ietf",
            "password": "password",
            "remarks": "sample",
            "server": "sample.ss.site",
            "server_port": 8388
        },
        {
            "method": "chacha20-ietf",
            "password": "password",
            "remarks": "sample2",
            "server": "sample2.ss.site",
            "server_port": 8388
        }
    ],
    "localPort": 1080,
    "shareOverLan": false
}

Solved. Import the file from File->import
