Previous month Measures not appearing in the table

[bbbbbiiiii]

Hi all, I am trying to make the previous month measures to appear even with the year selection on. However, I cant get the slicer not to apply the filter on the previous month. However, I need to show the table to filter according to the slicer filter. Can help?

These are the formula i used.

Current =DIVIDE(COUNT(Headcount[Attrition Date]),DISTINCTCOUNT(Headcount[EmpNo.]))

Previous = CALCULATE([Current],PREVIOUSMONTH([DATE]))

You have to use a separate calendar table and refer to it in your time intelligence functions.
