Keypad scan adds invalid keypads

[ident]

There is another bug causing phantom keypads 9 to 15 to appear after scanning  when Comfigurator 3.8.7 or 3.8.8 is used

This is different from the intial problem reported in this post

To workaround, Go to File > Update Defaults to update the default files (This needs an internet connection)

Also you can upgrade to ULT 7.057 which does not have this problem

To update this problem of detecting extran keypads 9 to 15 was fixed in firmware 7.057
