Need Help with Editor (Custom Cup)

Hi guys,

im trying to creat a custom cup for the pre-season. i want this cup to be played every year. i have done everything from cup-rules, picking teams, setting dates for the matches and so on.... it doesnt work!

i downloaded a file wich brings the "Emirates Cup" to the game, and it works. so i tried to change some minor things (more teams, more matches/dates) and there, it doesnt work....

can someone help me please?!
