Bug, persisted for years: Reminders in Calendar messed up

[Trinitylab]

Thanks, will post another screenshot once the thing happens, I found it intriguing:
one reminder with one date and time, old,
the other with, let's say, today date and time, new.
This has been noticed with the task shown in Calendar + reminder set.

You can check this yourself with the new database first. If not reproducible with the new one, check if reproduced with the database you use currently and if so, we'd need an empty copy of that database.

Will keep it in mind, thank you.
