Anyone else have strange issues with alexa?

I have it connected to ST hub so it can see my devices and have groups setup within the alexa app.

I have a group to turn all lights on but sometimes alexa only turns half of them on even though they are checked marked in the group. Them sometimes it will only turn a few of them off.

This seems to happen when you add a new device or re-name a existing device. Alexa still shows the old devices name or when i completely remove a device alexa still sees it.

I have re-moved devices from alexa only to have them re-appear, devices that have not been used in month and have been unpluged alexa still can see.

Is the google hub any better or is it just me?

With Google Home you can say “sync my lights” and it refreshes what has been selected in the ST app. Works fine.
