I've given it a go with the settings you've mentioned and was able to finish a 2 innings 20 over per innings match just fine, even starting at 6:30am.
One thing to mention, when you set up a new competition, it saves a copy of your match type in it - so if you've tried to make changes after you started that competition, then it wouldn't reflect them.
That probably wouldn't explain everything you're getting, but worth trying.
