powerBI graph not rendered correctly

Hello,

I'm creating a line graph:

  x-axis is date

  y-axis is a number <- Count of number of installs of CS

Now the "Count of number of installs of CS" is the same for all the dates.

The graph does not come up correctly

Problem line graph

These are the parameters I'm using

This is the data I'm using

Why is line graph wrongly summarising some values?
How do I fix this problem?
