Approval rule not working - Promotion

We are trying to build an approval rule in Transaction console → Promotion.

Below are the conditions :

Rule 1:

((Worker's Salary Details.Proposed Change Percentage == null) OR (Worker's Salary Details.Proposed Change Percentage < 15))  → Self approval ( Working as expected)

Rule 2:

((Requestor's Role Details.Role Name == "Comp role name") AND (Worker's Salary Details.Proposed Change Percentage != null) AND (Worker's Salary Details.Proposed Change Percentage >= 15)) → Self approval ( Not working)

Rule 3:

((Requestor's Role Details.Role Name != "Comp role name") AND (Worker's Salary Details.Proposed Change Percentage != null) AND (Worker's Salary Details.Proposed Change Percentage >= 15)) →  Application role Comp team( Working as expected)

_______________________________________________________________If an employee with the comp role is submitting the Promotion rule 2 and rule 3 both are getting triggered. in the transaction console the workflow is getting triggered 2 times. it is getting self approved but again another level of approval is getting triggered to the comp team (rule 3).Has anyone come across this issue ? .
