Chart uses wrong date

Hello Power BI-Community,

We are dealing with the following issue concerning our Recruiting Report:
In the underlying table, one row contains one application. There are separate columns for each of the various milestones in the process, i.e.:

• "Date when interview 1st stage scheduled", "Date when interview 2nd stage scheduled", "Date when further interview scheduled"
• "Date when interview 1st stage took place", "Date when interview 2nd stage took place", "Date when further interview took place"

  The report contains two charts: Number of interviews scheduled per month & Number of interviews took place per month. The issue is that interviews in 2nd stage or further are displayed in the month in which the interview 1st stage was scheduled/took place instead of being displayed in the month that they actually werde scheduled/took place

  Can anyone help with an explanation or a solution for our issue?

  Thank you in advance.
