Changing memory clock causes minimum memory clock to change

So when I change the GPUs memory clock, the minimum memory clock changes with it. Now the GPUs memory idle speed is what I set the maximum to, and I can no longer reduce my memory speed. Note: GPU3 and GPU4 I have yet to touch the settings on, which is why they can idle down to 150 Mhz.

 

NOTE: The GPU numbers of Afterburner do not match up the the GPU numbers of radeon settings.
