Why do I get: WARN : Duplicate field: 'SonosPlay_Save'

I have a working SetUp including some Sonos Players. The players have been discovered and added as Items using custom names(“PlayKueche”).
In the .Items files I have set serveral controls which are connected to the Players like:

Switch PlayKueche_Save "Save"(EG_Kueche) {channel="sonos:PLAY1:RINCON_xx1400:save"}

If I do restart OpenHAB the players get dircovered and I get for each used channels following log entries:

12:45:17.779 [INFO ] [smarthome.event.ItemAddedEvent      ] - Item 'PlayKueche_Save' has been added.
12:45:17.783 [INFO ] [home.event.ItemChannelLinkAddedEvent] - Link 'PlayKueche_Save-sonos:PLAY1:RINCON_xx1400:save' has been added.

followed shortly by:

12:45:18.678 [INFO ] [smarthome.event.ItemRemovedEvent ] - Item 'PlayKueche_Volume' has been removed.

However the last reported is omitted for all the “_Save” and “_Restore” channels, resulting in the following warning (which is repeated whenever a rule-file gets updated):

12:45:50.105 [WARN ] [.rule.jvmmodel.RulesJvmModelInferrer] - Duplicate field: 'PlayKueche_Save'. Ignoring 'org.eclipse.smarthome.core.library.items.SwitchItem'.

Am I on a wrong track?
BTW Item Linking simple mode is OFF.

It looks like a bug I have already declared.
