This EA is programmed to open only one trade at the time. It verifies if there are open positions and opens a new position only if there aren't other open positions.

I hope you understand.
I will gladly help you to "fix" this "problem". For this CCI EA, I think it's better to leave it like this. Please post other EAs that you need to modify and I'll do it for you.
There is no problem with your MetaTrader.

Bye.
