KPI

Hi, I have a small issue with my KPI. I am trying to compare data 2021 and 2020. I have correct number if i choose a table, but when I switch to the KPI, i get a tottaly different figure. Can anyone suggest any solutions please? In the picture bellow, I have tried to explain the situation. So the table visual in PowerBI shows 20 as a difference, but KPI displays 50. why?
