Netgear GS752TPS Slow after stack master election.

I have two GS752TPS switches stacked together using the standard Netgear stacking cable. An issue occurred after a power failure that resulted in the stack master rebooting and the second stack member /Opr Standby did an election and took control of the stack. Someone did a speed test and noticed that some workstations on the network were transmitting data at full speed and others were at approximately 1.5Mb data transfer speeds. After messing with the switch settings, VLAN settings etc.and finding nothing different between the two switches, I noticed that the Stack Master light was lit on switch 2 and was usually on switch 1. So I figured an election happened during the power failure and changed the stack master to switch 2. No problem as this is supposed to happen. I then noticed that all of the workstations plugged into switch 1 (the original stack master) were running slow (approx 1.5Mb) and the workstations connected to switch 2 (new stack master after the power failure) were running at full speed. So my question is: If an election happens and the stack master changes has anyone seen where the old stack master slows down to dismal speeds? The only way to correct the issue was so manually change the stack master back to switch 1 in the Web config and all is ok. Still it's alarming this would happen. Has anyone seen this and is it by design for some unknown reason?
