Sage No more pop-up window Show Reading Position Changes

All of a sudden pop-up window 'Show Reading Position Changes' resulting from Kobo Utilities plugin (in Calibre) stopped to pop up after Kobo USB connection (see former screenshot below about what it looked like).

Also attached is a screenshot of my 'Store or Restore Bookmark' item setup of 'Kobo Utilities' plugin.

What I miss?
