problem using reminder window. task reminder missing

[AJ]

maybe i'm too inexpirenced with reminder window but shouldnt all runing/setted reminders be shown in it?
example. rem in 5m but no in rem window. its a task, only in task list.
whats the cause of it and what and with witch reminder span is shown?
and how to fix it?
or does it only show from 2nd reminder after click on the pin?
i want/need to see reminders of next 24h in this window.
i'm very new to the feature show reminder window before alarm time.

the reminder got shown by 2nd or 3rd time setted/activated but disappeared before alarm after reopening the rem window and the in meantime activated alaram in 10m for other task also not showing. i dont get it, whats wrong?
newest build.
thx
i would rather prefer to see this reminders i a activatable list pulled down of a desktop clock. in next button it would make same but show all appt and/or tasks for 24h, but thats a idea for future.
i would sacrafise display space on left or right for this feature.
it would be a game changer which i hope could get first draft or simple version in one of next versions as i miss it hardest since ever.
thx

Reminders will appear only when their scheduled time is due. If not dismissed, they will remain visible in the Reminders window until you choose to snooze or dismiss them.

i expect to see the for today or next 24h before reaching time and remember someone here said it would go with opening the reminder window via the menu.
i kinda need to see todays reminders before, at least 1h and counting down.
i'm not fully sure how want to get the countdown but i need for some a countdown.
not sure if this needs to be a seperate option, like countdowns on in the reminder window via menu.
kinda every simplest tool offers countdowns.
i'm not sure yet if should show counting down next to appt/task for e.g. up to 1h or in the reminder window.

There is no such feature available at this time, unfortunately.
