10 speed campa will be compatible throughout all gruppos and all manufacturing years. There were no changes in cable pull. Only items to avoid are the quick shift ergopowers, shitty and artificially limited functionality. Always get ultra shift ergopowers. Not sure where your problem stems from. Give it a good clean and install new shifter cables?
