How to calculate percentages per month & use the KPI Status with History visual

Hello everyone,

I have two questions: 1) How can I calculate the right percentages in the example below?

                                   2) The KPI Status with History visual sorts the months in alphabetical order. How can I change this to chronological order?

I've created the table below with the formula from picture 2. I've found this formula on this forum from a post by . Although the formula seems to work, the calculated percentages are not right. For instance, in June (Juni) the value Yes (Ja) is 44,44% instead of 28%. What can I do to solve this challenge?

And besides this I cannot use the KPI status history visual properly because I am not able to sort the months in chronological order. What can I do in this particular case?

Note. I am not an expert yet. I am working with Power BI for 3 weeks now. Thanks in advance for your help.
