Why does regular salary retro element being triggered every pay period when the shouldn't

Hello Experts,

We have an instance where the regular salary element is consistently getting retro’d every payroll cycle, even when there have been no actual changes to the amount or related data. This behavior seems unexpected, as regular salary should not trigger retro pay unless there’s a valid change. Do you happen to know what might be causing this behavior?

Appreciate your help into this.

Thank you in advance.
