Unexpected number of substitution rules

Hi

We want to delete the substitution rules set for a specific id and are unable to do the same. The error is as below. We are on NWCE 7.3 SP7 version. We use BPM UWL connector. We tried checking the KMC_WF_SUBSTITUTE and did not find any entries for the specific ids that we were searching for. Any idea on how to resolve this error and to enable us to successfully delete the substitution rules.
