Phones and emails make duplication rows

Summary

I'm trying to add columns for emails and phones but instead of one line it's duplicating it

Hi,

I created an analysis in OTBI that shows employees phones and emails. So I created separate field for each phone type and email.

For example, for the Home mobile phone I used this formula - 

CASE WHEN "Workforce Management - Person Real Time"."Person Phones"."Phone Type Code" = 'HM' THEN "Workforce Management - Person Real Time"."Person Phones"."Area Code"|| '-' ||"Workforce Management - Person Real Time"."Person Phones"."Phone Number" END

For Work mobile phone - 

CASE WHEN "Workforce Management - Person Real Time"."Person Phones"."Phone Type Code" = 'WM'  THEN "Workforce Management - Person Real Time"."Person Phones"."Area Code"|| '-' ||"Workforce Management - Person Real Time"."Person Phones"."Phone Number" END
