Schedules cannot be modified or deleted

When I wanted to set the schedule, I accidentally set it incorrectly, but I found that I couldn't find any button to modify or delete it.
It's so bad.

Additionally, I noticed that the interval time can only be set to 1-360. When I enter 1440, it changes to 360, but when I enter 3600 and then enter, it immediately creates successfully. Although the displayed time is 360 minutes, its execution time seems to be only 360 seconds
