Why do bill reminders disappear if they go past due, but have not been entered in the register?

This happens to me once or twice a month; if I haven't added a bill/income reminder to the register, it disappears. It does not happen for all overdue reminders though. I find that what I have to do is go to the next month's reminder and schedule it to start at the overdue time, and then I can enter it. It just doesn't make sense that it disappears from the bill reminders (and also is missing from the calendar view, viewing in the past when it should have been due). I saw some other discussion that said to uncheck "Automatically add to transaction registers" in the Edit, Preferences, Downloaded Transactions menu, but it's already unchecked. It's a good thing that I remember that I didn't enter a bill, because I can't count on Quicken to remind me. How do I fix this problem?

Where do you look for those past due reminders?
In my account registers they typically show on the due date as if they were register transactions already, in bold face text.
Depending on settings, they'll also show at the bottom of the register in the Bill and Income Reminders tab.

In other views, e.g., the Home Dashboard, a classic Bill and Income Reminders view, the more recent Bills, Income & Transfers views they always show

Is it possible that, when you executed last month's reminder, instead of setting itself to next month, the due date skipped a month ahead?
In that case, what is your setting for xx in "Remind me [xx] days in advance"?
