Grouping problems

[elgringo]

I have several Zwave devices. A fibaro gen5 wall plug have created some associations with z wave node 255 and instance 255. But this node does not exists. I cannot remove them from the group configuration. Domoticz ask for a confirmation dialog but the gorups doe not get updated.

Tried a soft reset, manually edit the file (zwcfg) but this does not seem to work. See attachment. How can I update these false references?
