Most probably the difference is because you have placed the EAs at a different time on the Demo and the Live accounts.
I guess what you did is to test the EAs on a Demo, and you placed some of them on the Live account.
The moment you place the EAs on the Live you might have opened trades on the Demo.
And on the lice account they will open on the next signal.
So it might take a week or even more (depending on the strategies) to start matching from Demo and Live.
