[Koha] 21 day loan help

This has started on one of our servers, no matter what it defaults to 21 days. If i create rules to have a certain item type only be allowed 3 days loan, its still 21 days. We recently moved our server where one is running apache and the other is running the database and for some reason this instance is not working correctly. Anyone have suggestions? I am thinking of just doing a update with the latest to see if it fixes it. I am not sure how its coded in the system but I am assuming that the 21 is hard coded in the script and it just checks to see if there is any fine/loan entries in the database and to use them if they are there. Thanks. -Scott
