S5 Alarms in clock setting

[AC Question]

How do you turn off the alarm setting, that automatically silences an alarm after a minute, on the Samsung S5? My alarm always turn off after a minute, without me pressing buttons, and it shows on my notification screen, that the alarm has been "silenced". How do I turn that off, so that the alarm will continue to sound, until I turn it off manually?

I have the same issue too.
