Duplicate Perspectives

I had notice on my iPhone, there were TWO "Due Perspectives"in OmniFocus2. I couldn’t figure out how to remove the duplicate from my iPhone; but when I removed the only “Due Perspective” from the OmniFocus2 client on my MAC and then synchronized, the duplicate disappeared from my IPhone.

So, I can’t add a “Due Perspective” to my MAC client OmniFocus2 because then it will create another “Due Perspective” on my IPhone causing me to have duplicates.

Also, when I did have duplicate “Due Perspectives” on my IPhone and I deleted a task from one of the “Due Perspectives”, it automatically deleted the task from the other “Due Perspective”.

Any suggestions as to how I can create or have a “Due Perspective” on my MAC without it creating a duplicate on my IPhone?
