Not able to [Remove End Date] - NI Calculation Card Component

Summary:

Hello Experts, We're trying to process a payment for a leaver and hence remove the end date from Payroll Relationships. This didn't open the End Date on [NI] component card. When clicked on [Remove End Date], nothing changes. Is it possible to achieve through UI /HDL. If HDL is the only option, is there any query/template available?
