I'm running an Antminer from the latest batch and I'm noticing curious pool-switching behavior when multiple pools are configured.  With my older Antminer it always mines using the pools in order of priority, so it only uses the second one as a fallback if the first one is down.  With this new Antminer it seems to be alternating between configured pools?  That's not what I want.  How do I get back to the fallback functionality of the older Antminers?  Is anyone else seeing this issue?
