RuleSet: When editing a rule ,set fields are not matching

Good morning experts,

I have an issue with a RuleSet. My version is 9.40 codeless.

In my QA environment the RuleSet is working properly in the task of filling out the field according to another field when selected. In my Production environment I have the same RuleSet but I noticed a difference in a couple of the Field names.

When I try to match the field with in Prod with the field names that are in QA, the field names are not there to select.

I checked the tables in both environments and they match. My question is how can I correct the Prod environment to reflect the required field names that are in QA.
