Using MySet on OMD-E-M5

Ok, I must be slow because I'm simply not getting on how to select a preset MySet without saving it.

I have MySet 1 for single AF and trying to set MySet 2 for C-AF.  After I created MySet 1 and then changed the AF to C-AF, I then went to save it to MySet 2.

The problem I am encountering is now that I have MySet 2, if I now go back to try to select MySet 1, it ends up saving the C-AF to it.  For the life of me I can't figure out how to select a preset without actually overwriting it.

It's driving me nuts!
