Unable to create Multiple grade Rate - Type Salary, Bonus

Summary:

We have requirement where there is salary Range for each grade and Target bonus % defined for each Grade.

I am trying to create 2 grade rate Type , One for Salary ( where I was able to add all the relevant grades ) , Now while creating Grade Rate of Type Bonus , it gets submitted / Saved when the grades are not attached .

Once I attach the grade , i see the error " The value of the attribute RateObjectId isn't valid'

I am seeing the same error while creating Mexico Grade Rate , We are using same grade structure but different rate value based on Country
