Reset function not working properly

Hi, thank you for this awesome plugin !
I have a little issue with the timer.
When I reset my evergreen timers through the plugin settings (or through the editing page of an individual counter) then I refresh a page with the timer, at first this one is counting down again (as the reset worked), then when I refresh that same page again the timer is at 0. I don’t know what is happening here. I created a test page to show you that. Looking forward to hear from you soon.
Thank you in advance.
