2.9.1 cannot cancel timer

[jpalo]

Pressing Cancel below Timer on front page has no effect on the scheduled timer (start/stop), only the buttons change accordingly. After browser refresh timers remain as they were, also buttons below indicate timer is set.

I've been unable to replicate the issue, and no other users have reported this issue. What browser are you using? Could you try using a different browser / device?
