Wemo Bulb states showing incorrectly

I have two Wemo bulbs in lamps (hallway lamp and livingroom lamp) that are connected to a wemo bridge.

They’re configured in Openhab2 , on my sitemaps and work fine. Recently though, if I change the state (on, off) or brightness of either bulb, the non-changed bulb also shows the changes in the UI but not physically (i.e. only one will dim or turn on/off) but both will show the changed UI.
The logs show that both bulbs have received an ItemStateChangedEvent despite only one of them physically changing states.

At the same time, I’ve also noticed that if a rule is present inside the Wemo app that turns the bulb off by dimming, the switches in OpenHab won’t turn the item back on - I need to tap the dimmer slider to make the bulb respond.

I think there may have been a firmware update on the bridge about a week or two ago.

Does this happen to anyone else? how can I fix it?

Please file an issue at https://github.com/eclise/smarthome and I will have a look.
