TOPIC: Calendar Details Link not working

In DT Register 2.7.1c, which I just installed today, in the Calendar, the link to the Details View goes to:
component/content/ID but it needs to go to
component/content/article/ID
In any case it gets an error every time.

I'm trying to figure out a variety of other things, which may or may not be errors... folks, is it better to go get JEvents or can this calendar be configured?

Also, I don't understand the selections on the User Panel. When you select Paid or Not Paid, you get the same result. When you search and something is found or not found, you get the same result.
