Signalling 8 to refresh doesn't work

As the title says, script doesn't refresh when I signal 8 with pkill. But instead, if I run nwg-wrapper with --sig_refresh 7 flag, it does work if I signal 7. I have no idea why. Also, 7 is just random and 8 is the default of nwg_wrapper. Any help appreciated. Thanks.

I guess this is where things go wrong:

nwg-wrapper/nwg_wrapper/main.py

Line 229 in 89af959

parser.add_argument("-sr",

    parser.add_argument("-sr",
                        "--sig_refresh",
                        type=int,
                        default="99",
                        help="custom Signal number to refresh the script; default: 8")
