I posted this in the "Quicken for Mac v6.0 Released" discussion on November 23, but since no one has commented on my entry, I am posting in a new question to make this issue more visible.
In v6.0, the way that transaction reminders are shown was changed. There is how account settings are now edited:

All of the registers are now supposed to have the clock icon in the upper right corner just below the search bar. This is true for all my accounts, except for the debt accounts. Instead, there is a gear icon, which when clicked on brings you to the screen above. So there is no way to change how far in advance payments are shown in these accounts.
Am I missing something?
