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

Thanks
