Did you change any dates? Is this during an international window? If not, I'd suggest that changing the dates to a window would be something to test.
EDIT:
The official FIFA calendar suggests June isn't a period for internationals except certain named tournaments. I haven't looked around the editor enough regarding these dates but I'm sure that's doable.
