Hub link not syncing

Since the 2.0 upgrade my two hubitat hubs have had trouble staying in sync. the command is given by one hub to the other, but the second hub doesn't turn the lights off. If I go to the device page on both hubs, the master hub says the light is off, the slave hub says the light is on.

If I then manually turn off the light from the master hub, it sometimes will go ahead and turn the light off, even though it already reported it as off. other times I have to go to the slave hub to turn it off.

I don't know if this is related, but the device in question is a jasco z-wave switch with the generic z-wave switch dimmer driver. I also have it polled by the new polling app. the polling only seems to work every other time though (and quite consistently alternates back and forth)

pollResponse    ok       DEVICE      2018-11-24 11:01:40.972 PM EST
pollResponse    failed   DEVICE      2018-11-24 11:00:36.558 PM EST

not sure what to make of half the pollResponses failing or even what that means. The polling only seems to occur intermittently.

thanks
