Sorting issue : when based on calculated field

Hi! 

I have a seemingly simple issue regarding sorting in bar chart!

Issue 1: Documents count by Vendor

- When I just had a measure counting the documents DISTINCTCOUNT(DocumentID), it worked correctly.

- When I had to change the measure so that DISTINCTCOUNT(DocumentID&FiscalYear&CompanyCode), the sorting works initially, but when I toggle the screen, it gets reset each time. The same happens in Power BI service.

Issue 2: Amount by Vendor

- When I used the amount imported, it worked correctly.

- When I had to change the amount, to add Accounting Signs (i.e. Calculated column, if Credit, Amount*(-1)), the sorting works initially, but when I toggle the screen, it gets reset each time. The same happens in Power BI service.

In both cases, I made sure the datatype is identical and also the Power BI Icon is the same before and after the change.

TIA!
