Came here to report the same issue. I have an ultra-wide monitor and wanted to go from default 4 columns to 6. Options are there in the drop down menu, clicking them does nothing.
At least the made it so I could add the player information in v25 and that takes up some of the wasted space until this gets fixed.
I haven't tried changing other screens, ie team or my GM page, but those show as they did in v24 with moving my user.dat file from 24 to 25. The scouting page should have done the same, so maybe it's limited to that page?
