Element with custom Secondary Classification earnings not flowing to exempt

We have a secondary classification: "Federal and State Taxing Only" under Primary Classification: Supplemental Earnings that should be included in the Wage Basis rules but the balances for it should flow to Exempt. When we added this secondary classification to be included in the Wage Basis Rules, the elements with the associated element classifications mentioned here had the earnings flow from Gross to SUI Subject Withholdable, RSW and Taxable instead of Exempt.

How can I update the secondary classification so the earnings flow to Exempt for SUI ER? Currently, it is flowing from Gross to Exempt for FUTA, which is how we want SUI ER to flow as well.
