Incorrect number of examples in pie chart

Hi All,

It is my first post here and as you can think, I am new in PowerBI. I hope that you will help me to solve my problem. Bassicly I have a pie chart and table that should show the same number of examples. Below you can find a screen:

Green and red columns has been created thanks to measured and operations on x column. Pie chart has been created based on greed and red columns. Right now for June results are fine. In total there were 12 examples and in pie chart, total number is also 12. But X column shows the average of values. When I change it from ''Average'' to ''Don't summarize'', I have 30 examples like below:

Pie chart doesn't want to update green and red values. Do you know how I could solve this?

Best regards

Tom
