I can't be the only one finding the new attack/transfer to teammate box is a backward step.I had no problem with it before but several failed orders with the new system, even after clicking 'treat teammates as enemies'.

You may consider the need of getting your inner ear checked.

New? Nothing's changed about it. Can you describe what you're seeing?

As long as the "treat teammates as enemies" box is checked, it should attack your teammates. I've never heard of it not working.

Do you need to check the box Treat Teammates as Enemies if you select Attack Only?

You only need to check "Treat teammates as enemies". Attack Only is an entirely different thing - look it up on help.

There must be some slight change. I had no trouble before.

Perhaps you just need to go home and rethink your life.
