Urgent cross validation rule question

Summary

Need advice on cross validation question

Content

Hello:  I am in urgent need of advice for cross validation.  We have a rule submitted on a parent 2, and now a new parent 1 under the parent 2 needs a different rule.  I added the rule for the parent 1, but it is still being blocked by the parent2.  Is the only way to get it to work is to end date parent 2 and add a new rule for the parent 2's now under parent 1?
