Unable to get item seen as switchable

I am getting a strange error in the logs for an item.
I am not sure how to sole it, it seems like a very basic switch definition.

2018-06-22 19:19:14.667 [WARN ] [mon.registry.AbstractManagedProvider] - Could not update element with key _tags:presenceHome in ManagedMetadataProviderImpl, because it does not exists.

the item is defined like thus:

Switch presenceHome "Whos here"  	["Switchable"] 



I think that a fix is on the way:

It’s a warning and doesn’t actually affect the functionality and it should still work
A fix is on the way.

The switch works but the tag to exportt to Alexa, and other systemns seems to beignored so unable to discovery the switch on them.
But hopefully fix will be along soon.
