My Delivery Methods Reset, And Now Will Not Update

Im not sure how it happened, I updated the store to latest version of cs cart, all seemed ok. I was going to do some fine tuning to my delivery methods as I need to add some more. Well there is 3 currently, manually set. All the values were empty in the Shipping time and rates tab...

So I went to re enter them, it makes no difference in checkout though. The values are still in the database from the old settings, but for some reason it is not updating these or showing them in the rates tab>

Anyone have any ideas on fixing this?

thanks
