Found this in BF changelog if it helps;

- LibButtonFacade (Authors, pay attention!)
  - Core changes:
    - The "root" group is now called "ButtonFacade" instead of an empty string as to make it easier to access.
    - The separator for RegIDs is now an underscore instead of a "pipe". Additionally, all root addon groups will have a RegID matching the name that they're registered with. IE, instead of Bartender4 having a RegID of "|Bartender4", it will have a RegID of "Bartender4". All subgroups will have RegIDs that follow the "Addon_Group_Button" format.
    - The skin callback firing function will now return the addon's root group data if a group is not specified. This means that addon authors can call LBF:Group("Addon"):Skin(db.profile["Addon"].SkinID, ...) prior to calling it for their individual groups to ensure that ButtonFacade's GUI displays the current settings for the addon's root group correctly. Feel free to contact me if you're unsure how to implement this correctly or if it gives you problems/errors.
    - Any author attempting to write a LBF GUI will need to register their addon with LBF via the skin callback function. The addon *MUST* be registered as "ButtonFacade".

Hope to see a fix, thanks!
