I tried messing around with these options but I could not get what I wanted. Anyways I am happy with the results for the time being, though I might work on it later.
By the way, I came across another problem now. I want to correct the Copa Libertadores and Copa Sudamericana dates as they do not align with each other as they should. I extracted the .xml files for each and edited them separately, adjusting the fixture dates so they are correct. However, when testing in the editor, the fixtures are still played on the old dates. It feels like they are hardcoded. Do you know what causes this, or what can be done? I am going to test them in game now, I will update here if it works.
EDIT: the Libertadores and Sudamericana new dates are working in game. I guess it is just a bug in the editor.
