[Koha] Problem with issues after trying to setup issue rules...

[Les Means]

Hello friends,

We have been happily using Koha for most of this school year at our little 
college library here in Flint, Michigan. We are using Koha 2.2.5 on Fedora 
Core 3. It has been going quite well, until I started messing with the 
issuing rules last week. The librarian was doing all the calculation of 
overdue fines by hand, and I knew Koha must have a utility for automating 
that process, so I began to play around with the "Issue Rules" page in 
Parameters, which to that point was totally empty. I attempted to fill in the 
fields for the different types of books and the different types of borrowers. 
All of a sudden no matter what kind of book or what kind of borrower, I began 
to get an error message upon issuing every book that says: "I need 
confirmation before issuing! Too many issues! (Already issued/ max: a 0/0) 
Confirm issue? don't issue?"

Additionally, the program no longer assumed that the book's due date was three 
weeks from today, but assumed it is due tomorrow, and the correct due date 
must be selected for every book! (Librarian very upset over this one!)

I decided it was better before I started playing around with things, so I 
deleted all issuing rules, making every field empty, as before, trying to 
restore it to the previous state of (mostly) bliss.

Unfortunately, we still are getting the described warning message with every 
issue, and still have to manually enter the correct due date for every book, 
which is totally unacceptable to the librarian, because it takes her three 
times as long to issue each book.

Is there a fix for this (aside from banning me from the library?)

Thanks and blessings be upon thee if you can save me from this mess!
