Problem with all prices

[scaredycat]

I have a save file 'Sheffield Wednesday' which I've been playing for years from time to time. I'm in 2017 and all of a sudden, I saw my player's value jumped like 30%. Before even I felt excited, I sensed that there should be a problem. I had bought the player for € 6M but in history it showed € 9M. I also remember most of my players' salaries and they were also up around 30%. I was also checking world class footballers and saw that their values jumped 10-15M as well. Last but not least, my transfer budget also went up from 35M to 50M and my wage budget from 72M to 105M. Everything went up, literally. It might not seem to be an issue but I somehow lost my joy because of this. Is there a way to fix it? Thank you for reading.
