I have a 6 button kpl which was acting up after making a small change. After trying to restore, factory reset then restore, and removing from scenese and replacing in scenes, I gave up.

 

I removed it from all scenes then removed it from ISY completely.

 

I factory reset it and readded it to ISY and redid all of the scenes. It is working again, however, in the tree of devices, all of the sub-buttons (A,B,C,D) show up as individual devices instead of in a sub-tree. Why is this happening?

 

I also tried clearing the Java cache.

By default, each node of a multi-node device gets its own entry on the device tree. To display them together, right-click on the main on/off button and select the Group option.

Curious. I never had to select that option before, it defaulted to it. They must have changed the default sometime from when I first added my KPL's to now.

 

Thanks for pointing out that rather obvious but yet missed solution.

I think I noticed this change in one of the recent updates. I recall, also, the option to expand (mouse click?) the primary button to show the links.

You do have to select that option in 2.7.15. They are not combined by default.
