Lookup Transformational rule UNDO

Hello. I have a set of Lookup Transformational rules. I have tried to load a mass upload for multiple lines of transformational rules through a trx file. I had a message saying the load has been completed with errors. However when I try to search for one rule I can't find it in the set of rules. When I try creating one of them manually it won't let me create it as it says it exists already, even though it doesn't show in the rule set. How can I undo what I did? How can I sort it out. A lot of people are depending of these rule set as it helps with Data extraction. Please support.
