Timers are fixed (a HTML formatter changed the format of some text).
As for the hysteria, if the system says that it's sending a signal then it'll be sending a signal. I've just tested it locally and it is OK.
Are you changing the GPIO when you set it in hysteria mode? Can you run:
when it should be 100% to see what it is doing, and provide the output of the "getstatus" page when it's on.
